Doppler (pt 1)

Is a change in the observed or received frequency of a wave because of the motion of the source or observer or receiver

The red dot represents a __ originating sound waves traveling in all directions equally

Since the source is not moving the frequency and wavelength are the __ in all directions

Regarding the doppler effect, if the frequency is doubled then the wavelength is ___

What happens to the frequency and wavelength in this image?

• Frequency halves, wavelength doubles

• Frequency doubles, wavelength doubles

• Frequency doubles, wavelength halves

• Frequency halves, wavelength halves

Regarding the doppler effect, high frequency = ___ pitch

Regarding the doppler effect, low frequency = ___ pitch

Short wavelength, high pitch = __ frequency

Long wavelength, low pitch = ___ frequency

Wave forms get closer at the __ of the moving source
