# How do you find the speed of sound in air experiment?

## How do you find the speed of sound in air experiment?

Signal your friend to bang the two blocks together hard. Start the stopwatch as soon as you see the blocks hit each other. Press stop as soon as you hear the sound from the blocks. Calculate the speed of the sound by dividing the distance between you and your friend by the elapsed time.

## What is the actual speed of sound in air for this lab?

At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,235 km/h; 1,125 ft/s; 767 mph; 667 kn), or a kilometre in 2.9 s or a mile in 4.7 s.

How do you find the speed of sound in a lab?

SPEED=DISTANCE/TIME. To work out the speed of the sound in metres per second, divide the distance in metres by the average time in seconds. For example 170 metres divided by 0.50 seconds = 340 m/s.

What is air speed?

Selected Sound Speeds in Gases

Gas Temperature (°C) Speed in m/s
Air 0 331.5
Air 20 344
Hydrogen 0 1270
Carbon dioxide 0 258

### What is the speed of sound in this metal?

Table One: Sound Speeds in Solids

Sound Speed* Shear Wave (25°C)
Steel, 1% Carbon, hardened 3,150 10,335
Carbon Steel 3,230 10,598
Mild Steel 3,235 10,614
Steel, 1% Carbon 3,220 10,565

### How do you find the speed of sound in air with temperature?

If the temperature is TC = 20 °C (T = 293 K), the speed of sound is v = 343 m/s. The equation for the speed of sound in air v = √γRTM can be simplified to give the equation for the speed of sound in air as a function of absolute temperature: v=√γRTM=√γRTM(273K273K)=√(273K)γRM√T273K≈331m/s√T273K. v=fλ.

Does air have speed?

For typical air at room conditions, the average molecule is moving at about 500 m/s (close to 1000 miles per hour). At higher temperatures the molecules have more energy and are moving faster than at lower temperatures, hence the speed of sound at higher temperatures is faster than at lower temperatures.

Why is the speed of sound important?

The speed at which small disturbances travel through a medium. The speed of sound is important because it is a measure of the shortest time in which a pressure change con be transmitted from place to place.

#### How do you calculate the speed of sound in a gas?

Solution: The speed of sound in a gas is given by v=√γRT/M.

What is the speed of sound in air at 0 C?

approximately 344 m/sec
The speed of sound varies depending on the type of elastic medium it is propogated in. The speed of sound in dry air at a temperature of 0 degree C is approximately 344 m/sec (1130 ft/sec).

How can you find the speed of sound in air?

The formula to find the speed of sound in air is as follows: v = 331m/s + 0.6m/s/C * T v is the speed of sound and T is the temperature of the air. One thing to keep in mind is that this formula finds the average speed of sound for any given temperature.

## What is the approximate speed of sound in the air?

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.

## How fast does the speed of sound travel in the air?

Speed of sound. In an exceptionally stiff material such as diamond, sound travels at 12,000 metres per second (27,000 mph); (about 35 times as fast as in air) which is around the maximum speed that sound will travel under normal conditions.

What is the value for speed of sound in air?

The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,235 km/h; 1,125 ft/s; 767 mph; 667 kn), or a kilometre in 2.9 s or a mile in 4.7 s.
