# What is the velocity of sound in air?

Since the molecules vibrate faster, sound waves can travel more quickly. The speed of sound in room temperature air is 346 meters per second. This is faster than 331 meters per second, which is the speed of sound in air at freezing temperatures.

Accordingly, what is the speed of sound in air and 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).

Why is the velocity of sound greater in water than in air?

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 velocity of sound in air at room temperature?

The speed of sound in air is approximately 331.5 m/s at 0 °C or around 1200 km per hour. The speed of sound through air is approximately 343 m/s at normal room temperature, which is at 20 °C. The speed of sound through air is 346 m/s at 25 °C. The speed of sound in air is approximately figured out by the formula …

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

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.

## Which is faster the sound of light or sound?

The standard metric for the speed of light is that of light traveling in vacuum. This constant, known as c, is roughly 186,000 miles per second, or roughly one million times the speed of sound in air. According to Einstein’s work, matter and signals cannot travel faster than c.

## 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.

## What is the speed of sound in water under average conditions?

The term is commonly used to refer specifically to the speed of sound in air. At sea level, at a temperature of 21 degrees Celsius (70 degrees Fahrenheit) and under normal atmospheric conditions, the speed of sound is 344 m/s (1238 km/h or 770 mph).

## What is the velocity of sound in air at a temperature of 30 C?

## What is the velocity of sound in air at room temperature?

The speed of sound in air is approximately 331.5 m/s at 0 °C or around 1200 km per hour. The speed of sound through air is approximately 343 m/s at normal room temperature, which is at 20 °C. The speed of sound through air is 346 m/s at 25 °C. The speed of sound in air is approximately figured out by the formula …

## 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.

## How fast is sound in air?

332 metres per second

## 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 is the speed of sound in the air?

343 meters per second

## How does density affect the speed of sound?

Similarly, it is harder for sound to pass through gases than through liquids, because gaseous molecules are farther apart. 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.

1,225 km/h

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

1498 meters per second

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

The speed of light is much faster than the speed of sound. Sound moves at 343 metres per second (thats about 770 miles per hour!) The speed of light is a little trickier. In a vacuum it is roughly 300 000 000 metres per second (so nearly 900 000 times faster than sound!)

## What is the speed of electricity?

Therefore, the speed of electricity in a 12-gauge copper wire is 299,792,458 meters per second x 0.951 or 285,102,627 meters per second. This is about 280,000,000 meters per second which is not very much different from the speed of electromagnetic waves (light) in vacuum.

## What is the speed of a bullet?

The problem is that sound travels at 768 miles per hour (1,126 feet per second)—about half the speed of the bullet. In this case, the bullet would hit you before you even heard the gun fire off.

## How fast does the speed of light travel?

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. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.

## How does sound travel?

Sound vibrations travel in a wave pattern, and we call these vibrations sound waves. Sound waves move by vibrating objects and these objects vibrate other surrounding objects, carrying the sound along. Sound can move through the air, water, or solids, as long as there are particles to bounce off of.

## Who broke the sound barrier in an airplane?

Chuck Yeager is an American test pilot who was the first person to break the sound barrier — the point where a speeding object (such as an airplane) passes the speed of sound. Yeager made his history-setting flight on Oct. 14, 1947 in an airplane he dubbed Glamorous Glennis, after his first wife.
