A sound wave a frequency of 20 kHz emerges through a circular opening that has a diameter of 0.78 m. Concepts: The diffraction angle for a wave emerging through a circular opening is given by sin(theta) = 1.22 /D, where is the wavelength of the sound and D is the diameter of the opening. What is meant by the diffraction angle? the angle that the sound wave bends away from the center before passing through the opening the location of...

When the source of a wave and an observer move either towards or away from each other the observed frequency of the wave will be different from the frequency at which the wave is emitted. For example, if you are standing by the side of the road and a police car with a siren passes by, the frequency of the sound you hear will be higher when the car is moving towards you and lower when it is moving away...
