## What does sound travel fastest through?

Sound waves can be described by the wavelength and frequency of the waves. Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster.

## What is the fastest possible speed of sound?

Scientists have discovered the fastest possible speed of sound, a zippy 22 miles (36 kilometers) per second. Sound waves move at different speeds in solids, liquids and gases, and within those states of matter — for instance, they travel faster in warmer liquids compared with colder ones.

## How fast is sound in a vacuum?

The speed of sound in a vacuum is zero meters per second, as sound cannot travel in a vacuum. Sound is a wave, which means it spreads through the vibration of particles in a medium, such as water or air. Since a vacuum is empty space, there is no medium for the sound to travel through.

## In which material will sound travel the fastest *?

The speed of sound is faster in solid materials and slower in liquids or gases. The velocity of a sound wave is affected by two properties of matter: the elastic properties and density.

## What material does sound travel slowest?

The speed of sound depends on the medium in which it is transported. Sound travels fastest through solids, slower through liquids and slowest through gases.

## How far can voice travel?

The normal intelligible outdoor range of the male human voice in still air is 180 m (590 ft 6.6 in). The silbo, the whistled language of the Spanish-speaking inhabitants of the Canary Island of La Gomera, is intelligible under ideal conditions at 8 km (5 miles).

## How fast is a light year in mph?

In a vacuum, light travels at 670,616,629 mph (1,079,252,849 km/h). To find the distance of a light-year, you multiply this speed by the number of hours in a year (8,766). The result: One light-year equals 5,878,625,370,000 miles (9.5 trillion km).

## How fast is the speed of dark?

Darkness travels at the speed of light. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light.

## How fast does Flash run?

## Does sound travel in water?

Thus sound waves travel much faster in water than they do in air. In freshwater at room temperature, for example, sound travels about 4.3 times faster than it does in air at the same temperature. … Sound keeps its energy longer when traveling through water because the particles can carry the sound waves better.

## Is there sound on the moon?

The air here on Earth allows sound waves to move from one point to another (sound can also move through water, steel, earth, etc… it just requires that particles/atoms/molecules are touching one another). … Thus there is no sound on the Moon.

## Where does light travel fastest?

Light waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water.

## What is the speed of sound in dry air at 0?

## How long can sound waves travel?

Media. Sound waves can travel through any material, but not in a vacuum, which is why there is no sound in outer space. The speed of sound in air is about 330 m/s, meaning that it covers a mile in about five seconds.

## How many Earth years is a Lightyear?

A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). One light year is equal to the distance that light travels in one year (it is about ten trillion kilometers, or six trillion miles). One light years is equal to approx 6.5×10^5 earht s years.

## Can you hear a scream from a mile away?

In free space, sound level drops off as the square of the distance. For simplicity, let’s use 1000 km, which is a bit more than 500 miles. If the sound level is 120 dB SPL at 1 m, at 1,000,000 meters it would be 10^12 times, or 120 dB lower—which means 0 dB SPL. 0 dB SPL can be just heard under ideal conditions.

## What is the farthest a human can hear?

The commonly stated range of human hearing is 20 to 20,000 Hz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea.

## Is anything faster than light?

No. The universal speed limit, which we commonly call the speed of light, is fundamental to the way the universe works. … Therefore, this tells us that nothing can ever go faster than the speed of light, for the simple reason that space and time do not actually exist beyond this point.

## Can humans travel at the speed of light?

So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. … So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.

## How fast is a shadow?

There is no limit to the speed that an image or shadow can move at. The shadow appears because you’re blocking the light from the Sun to hit the ground. Therefore you can calculate the time it takes to appear dividing the distance from your body to the ground by the speed of light (300,000 km/s).

## What is the fastest thing in the universe?

Laser beams travel at the speed of light, more than 670 million miles per hour, making them the fastest thing in the universe.

## Are shadows faster than light?

In principle, shadows can move faster than the speed of light. … When a shadow is bigger than the object casting it, it moves at a greater distance but in the same amount of time. If the shadow is large enough, it could move across the surface faster than light.

## How fast is Naruto in mph?

The Light Fang is said in the databooks to travel at the speed of light. Since Naruto dodged this attack, Naruto would be > 671,000,000 miles per hour at the end of the series.

## Can you see a fart in space?

When astronauts are not in the space suit and floating about, the fart smell is exaggerated by the lack of airflow from the recycled air used and its inability to mask any smell. … As per your second question on the ability to thrust about in space from a fart, this is very near impossible.

## Why can’t you whistle on the moon?

When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but the other astronauts would not hear the noise. … Because there is nothing out in space (like an atmosphere), the sound waves from one astronaut’s whistling can’t travel over to the other astronaut’s ears.

## Can you hear yourself talk in space?

No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.

## How fast is the black flash?

Powers and Abilities

## How fast is Sonic the Hedgehog?

Based on his namesake, which means “relating to the nature of sound,” Sonic has the capability to run at the speed of sound, which travels at approximately 767 mph. In the live-action film, however, Sonic is shown to be traveling at a much slower rate early on in the film.

## Can sound travel through glass?

Glass is rigid, and its massiveness is limited by transparency requirements that keep it thin. Glass transmits a lot of sound energy at its resonant frequency and at low frequencies. Laminated glass and insulated glazing units both reduce sound transmission through glass by reducing resonance and adding air-space.

## How far can whale sounds travel?

A Traveling Music

One of the interesting things about the humpback whale song is how far the song can travel. Researchers estimate that some of the lowest frequency sounds can travel through the ocean as far as 10,000 miles without losing their energy.

## Can sound pass through wood?

Sound travels even faster through solids because the molecules in solids are more tightly packed together than they are in air. For example, sound travels at 8,859 miles per hour through wood.

## Why is it so quiet after a snowfall?

That’s because snow absorbs sound, so when a fresh blanket of snow covers the landscape it absorbs many of the sound waves, making it seem quieter outside, according to AccuWeather. … Those spaces absorb sound waves, creating a quieting effect over a blanket of snow.

## Can sound go through metal?

Solids: … This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air. The exact speed of sound in steel is 5,960 meters per second (13,332 mph)!

## Can sound travel through empty space?

Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.

## Is lightning slower than sound?

Yes! But you see lightning before you hear thunder because light, which travels a million times faster than sound, arrives almost instantly. … Sound, on the other hand, takes about five seconds to travel one mile.

## Is time Travelling possible?

In Summary: Yes, time travel is indeed a real thing. But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.

## What if the speed of light was infinite?

If the speed of light was infinite, all points in the universe would be able to communicate with each other instantaneously. We wouldn’t be able to tell which stars are further away or older etc. Our universe would be one instantaneous here and now. No past, no present and no future.
