Waves speed and phase speed

1. Wave speed and Phase speed

2. #Wave Speed

3. Effect of medium
•Sound wave→Faster in solid
→then liquid and then gases.
•While the density of medium also effects the speed of
sound,the elastic properties have a greater influence on the
medium.
•The density of medium is the second factor that effect the
speed of sound.

4. • The phase velocity of a wave is the rate at which the
phase of the wave propagated,the product of the
frequency times the wavelength.
• This is the quantity that is determined by methods using
interference.
• In a dispersive medium it differs from the group speed.
Also called:wave speed or wave velocity.
