how to calculate mechanical wave velocity. Practice using a displacement graph and wave speed to find the frequency and wavelength of a wave. Compression and expansion of the acoustic wave Particle velocity vx y z t Acoustic pressure px y z t which is zero if there is no wave For longitudinal waves it is straightforward to relate the acoustic pressure to the underlying particle velocity where Z rc is called the characteristic impedance This is a like VIR Note that.

The continuum is made up of gases as sound waves liquids or solids including the Earth. Consider an ocean wave with a wavelength of 3 meters and a frequency of 1 hertz. Use the mass of the hanging weight M to calculate the tension T in the string.
Speed Wavelength x Frequency.
Suppose y A sin kx ot represents our traveling wave. Over an additional time t 2 the point will have moved an additional distance x 2 and since were looking at the same point this means y x 1 x 2 t 1 t 2 C also. Well its the velocity of any point on the wave so pick one where y x 1 t 1 C say. The wave velocity v is the velocity at which the shape of the wave propagates in space.
