What is the formula for speed of sound in air?
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. v = γ R T M = γ R T M ( 273 K 273 K ) = ( 273 K ) γ R M T 273 K ≈ 331 m s T 273 K . v=fλ.
What is the formula for how the speed of sound changes with temperature?
Section Summary. The relationship of the speed of sound vw, its frequency f, and its wavelength λ is given by vwfλ, which is the same relationship given for all waves. 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 .
What is the speed of sound in room temperature air?
346 meters per second
The speed of sound at 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.
What is the speed of sound at room temperature?
The speed of sound at 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. The speed of sound is also affected by other factors such as humidity and air pressure.

What is the speed of sound in air at 35 C?
Question: What is the speed of sound at 35°C? (352 m/s)What is the speed of sound at -20°C? (319 m/s)A 320 Hz tuning fork will produce a wave of what wavelength in air at 22°C? (1.1 m)We see a bolt of lightning and 4 seconds later we hear the thunder.
How do you calculate the speed of sound waves?
speed = distance/time If a sound wave were observed to travel a distance of 700 meters in 2 seconds, then the speed of the wave would be 350 m/s. A slower wave would cover less distance – perhaps 660 meters – in the same time period of 2 seconds and thus have a speed of 330 m/s.
What is the speed of sound at an air temperature of?
about 343 metres per second
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. It depends strongly on temperature as well as the medium through which a sound wave is propagating….Speed of sound.
