# What is the velocity of sound in air and water?

A: Sound travels around 1500 meters per second in water. It varies slightly with temperature. This is much faster than the velocity of sound in air, which is only about 340meters per second.

Similarly, it is asked, how fast is sound in water?

For example, (as noted above), sound travels at 343 m/s in air; it travels at 1,484 m/s in water (4.3 times as fast as in air); and at 5,120 m/s in iron (about 15 times as fast as in air).

What is the speed of sound in the ocean?

Sound travels about 1500 meters per second in seawater. Sound travels much more slowly in air, at about 340 meters per second. The speed of sound in seawater is not a constant value. It varies by a small amount (a few percent) from place to place, season to season, morning to evening, and with water depth.

## What is the velocity of sound in sea water?

Sound travels about 1500 meters per second in seawater. Sound travels much more slowly in air, at about 340 meters per second. The speed of sound in seawater is not a constant value. It varies by a small amount (a few percent) from place to place, season to season, morning to evening, and with water depth.

## What is the speed of sound in fresh water?

## What is the speed of sound in a vacuum?

Since a vacuum is empty space, there is no medium for the sound to travel through. The speed of sound in air mainly depends on the temperature of the air. On average, it is about 343 meters per second (1,125 feet per second), which is faster than the speed of sound in a vacuum.

## Why is the speed of sound faster in water?

In water, the particles are much closer together, and they can quickly transmit vibration energy from one particle to the next. This means that the sound wave travels over four times faster than it would in air, but it takes a lot of energy to start the vibration.

## What is the speed of light in the water?

As an approximation, it is about 3/4 of its speed in a vacuum, or 225,000,000 meters per second. As Dipen said, you’d really need to know the index of refraction which depends on its temperature, etc. The index of refraction of water is about 1.33, so the speed of light in water is (c/1.33) = 2.25E8 m/s.

## How many miles per hour is the sound?

This method is based on the fact that light travels much faster than sound through the atmosphere: Light travels at 186,291 miles per second (299,800 km/s), whereas the speed of sound is only about 1,088 feet per second (332 meters per second), depending on air temperature.

## How fast is sound in air?

332 metres per second

## How fast do you have to go to break the speed of sound?

In dry air at 20 °C (68 °F), the sound barrier is reached when an object moves at a speed of 343 metres per second (about 767 mph, 1234 km/h or 1,125 ft/s).

## What is the velocity of the light?

: a fundamental constant that represents the speed of electromagnetic radiation in a vacuum and equals approximately 2.9979 × 1010 centimeters per second.

## Can sound travel in a vacuum?

But it seems that in some circumstances, sound can jump between objects in a vacuum after all. 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.

## What changes the speed of sound?

Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly. The speed of sound in room temperature air is 346 meters per second.

## How much faster is the speed of light than sound?

The speed of sound through air is about 340 meters per second. (The speed of sound in water is about 4 times faster than this). The speed of light in air is about 300 million meters per second.

## How does sound travel in the ocean?

Water temperature and pressure determine how far sound travels in the ocean. While sound moves at a much faster speed in the water than in air , the distance that sound waves travel is primarily dependant upon ocean temperature and pressure. The whale produces sound waves that move like ripples in the water.

## How quick is the speed of light?

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph.

## What is the speed of sound at sea level in feet per second?

1,100 feet per second

## How are lake waves created?

Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.

## What is a sonic boom and what causes it?

A sonic boom is a loud sound kind of like an explosion. It’s caused by shock waves created by any object that travels through the air faster than the speed of sound. Sonic booms create huge amounts of sound energy. When an object moves through the air, it makes pressure waves in front of and behind it.

## What is the speed of sound in iron?

So iron has a density of about 7,800 kg/m , while mercury has 13,600 kg/m , but the speed of sound is 1,450 m/s in mercury and 5,130 m/s in iron, so mercury has a higher density, but sound travels slower in it.

## What type of wave is a sound wave?

In this case, the particles of the medium move parallel to the direction that the pulse moves. This type of wave is a longitudinal wave. Longitudinal waves are always characterized by particle motion being parallel to wave motion. A sound wave traveling through air is a classic example of a longitudinal wave.
