# What experiment could you do to measure the speed of sound?

## What experiment could you do to measure the speed of sound?

Clap-echo method This method involves measuring the time taken for you to hear an echo from a sharp clap. You stand a long distance from a wall, clap, and listen for the echo. The distance travelled is twice the distance from you to the wall (because the sound has to travel to the wall and back).

### How fast does sound travel in FPS?

Speed Of Sound to Foot Per Second Conversion Table

Speed Of Sound Feet Per Second
0.7 sound 787.73 ft/s
0.8 sound 900.26 ft/s
0.9 sound 1,013 ft/s
1 sound 1,125 ft/s

#### How do you find the speed of sound and distance?

The speed of the sound wave is 340 m/s. The distance can be found using d = v • t resulting in an answer of 25.5 m. Use 0.075 seconds for the time since 0.150 seconds refers to the round-trip distance.

What instrument is used to measure the speed of sound?

A sound velocity probe is a device that is used for measuring the speed of sound, specifically in the water column, for oceanographic and hydrographic research purposes.

Does sound travel at constant speed?

The speed of sound in the atmosphere is a constant that depends on the altitude, but an aircraft can move through the air at any desired speed.

## Can sound travel faster than the speed of sound?

Faster than sound? As the speed of sound has a finite (and not so very great after all) value, in theory, an object that makes that sound can catch up with its own “noise” and even go faster.

### Which equation can be used to calculate the speed of sound?

The equation for the speed of sound in air v=√γRTM v = γ R T M 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≈331ms√T273K.

#### Can you identify the factors that affects the speed of sound?

The speed of the sound depends on the density and the elasticity of the medium through which it travels. In general, sound travels faster in liquids than in gases and quicker in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.

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

v=√Bρ. The speed of sound in a solid the depends on the Young’s modulus of the medium and the density, v=√Yρ. where γ is the adiabatic index, R = 8.31 J/mol • K is the gas constant, TK is the absolute temperature in kelvins, and M is the molecular mass….Speed of Sound in Various Media.

Medium v (m/s)
Steel 5960

How long can sound waves travel?

The speed of the sound wave is 340 m/s. The distance can be found using d = v • t resulting in an answer of 25.5 m. Use 0.075 seconds for the time since 0.150 seconds refers to the round-trip distance. 2.

## How do you find the speed of sound when given wavelength and frequency?

The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength.

### Can you make the speed of sound faster?

The speed of a sound wave depends on the properties of the medium through which it moves and the only way to change the speed is to change the properties of the medium.

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

What Is the Speed of Sound in Fps? The speed of sound, known as Mach 1, varies depending on the medium through which a sound wave propagates. In dry, sea level air that is around 25 degrees Celsius, Mach 1 is equal to 340.29 meters per second, or 1,122.96 feet per second.

What are the methods of measuring speed of sound?

Other methods. In these methods, the time measurement has been replaced by a measurement of the inverse of time ( frequency ). Kundt’s tube is an example of an experiment which can be used to measure the speed of sound in a small volume. It has the advantage of being able to measure the speed of sound in any gas.

Can you measure the speed of sound with a PC oscilloscope?

Measuring the Speed of Sound. This experiment describes the use of a PC oscilloscope to measure the speed of sound. The ADC-212 used in this experiment has now been discontinued but the experiment can be performed with any PicoScope oscilloscope that has at least 2 channels.

## What is the 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; 7672.9 s
