How do you find the speed of sound in air GCSE?
How do you find the speed of sound in air GCSE?
The speed of sound in air is often measured using the following method:
- two people (person A and person B) are placed a distance apart, eg 100 metres.
- person A fires a starter’s pistol.
- person B times the difference between seeing the flash of the gun and hearing the sound – this is measured in seconds.
What is the formula of speed of sound in gas?
Solution: The speed of sound in a gas is given by v=√γRT/M.
What is the speed of sound in?
speed of sound, speed at which sound waves propagate through different materials. In particular, for dry air at a temperature of 0 °C (32 °F), the modern value for the speed of sound is 331.29 metres (1,086.9 feet) per second.
How do you calculate the speed of sound in air?
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. You have calculated the speed of sound!
How do you find the speed of sound in air?
Assuming the speed of sound in air is 345 m/s, determine the wavelength of the sound corresponding to the note of middle C. Let λ = wavelength. Use v = f • λ where v = 345 m/s and f = 256 Hz. Rearrange the equation to the form of λ = v / f….The Speed of Sound.
| a. one-ninth | b. one-third |

| c. the same as | d. three times larger than |
How do you calculate the speed of sound in a solid?
v = β ρ . The speed of sound in a solid the depends on the Young’s modulus of the medium and the density, v=√Yρ. v = Y ρ .
How do you calculate the speed of sound and temperature?
Speed of sound c ≈ 331.3 + (0.6 × ϑ) in m/s. That gives e.g. at a temperature of ϑ = 20°C a speed of sound of: c ≈ 331.3 + (0.6 × ϑ) = 331.3 + (0.6 × 20) = 343.3 m/s….
| Temperature ϑ (theta) °C | ↔ | Speed of sound v m/s |
|---|---|---|
| Frequency f Hz | ↔ | Wavelength λ m |
What is the speed of sound at 35000 feet?
about 660 mph
At 35,000 feet, the cruising altitude of a typical passenger jet, sound travels at about 660 mph (1,062 kmph).
What is the formula for calculating speed of sound and temperature?
In air, the speed of sound is related to air temperature T by vw=(331m/s)√T273K v w = ( 331 m/s ) T 273 K . vw is the same for all frequencies and wavelengths.
How do you calculate the speed of sound?
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 approximate speed of sound?
The speed of sound in air is approximately 344 meters/second, 1130 feet/sec. or 770 miles per hour at room temperature of 20oC (70oF). This speed is primarily a function of temperature.
What is Newton’s formula for speed of sound?
Newton calculated the formula speed of sound, assuming the transfer of sound waves through a medium to be an isothermal process. According to this formula, v = √P ρ. The results obtained by using this formula did not match with the actual value of the speed of sound.
What two factors determine the speed of sound?
The speed of sound is influenced by several factors, including medium, density and temperature. The rate at which sound waves moves varies widely from one situation to the next and can change dramatically in a short period of time.
