how to find out wave speed. On the other hand if the crest of an ocean wave moves a distance of 25 meters in 10 seconds the same amount of time then the speed of this ocean wave is 25 ms. The speed of a wave equals its frequency times wavelength.

How close were you. Sound moves through the air at a speed of around 343 meters per second which is 12348 kmh or 767 mph at 20 C 68 F. It can be shown that the speed of a longitudinal wave in the bar is given by The relation between pressure P and volume V is Where N is the number of molecules in volume V k B is the Boltzmann constant and T the temperature of the gas in Kelvin.
The fact that amplitude frequency and wavelength do not affect wave speed is demonstrated.
The speed of a wave can be calculated using the equation. You may see it as miles per. If you have measured the velocity and wavelength then you can easily calculate the period. Speed frequency wavelength Here the frequency is 256Hz.
