Define Frequency.
a measure of how many wavelengths pass a given point per second
What is the resulting direction of a surface wave?
Circular
When traveling from a solid to air, what would a sound wave be expected to do?
slow down
What is the Doppler effect used to do in hospitals?
Monitor Blood flow
When traveling from air to a solid, what would you expect a sound wave to do?
Speed up
The relationship between frequency and wave speed is found which the equation?
v=f (LAMBDA)
OR
wave speed= frequency * wavelength
