The part of a longitudinal wave where the particles of the medium are close together.

• rarefaction
• compression
• crest
• trough

A part in a longitudinal wave where the particles are spread apart

• compression
• rarefaction
• crest
• trough

Which of the following would you hear as a low pitched sound? 

• sound wave with a frequency of 50 Hz
• sound wave with frequency of 10,000 Hz
• sound wave with an intensity of 10 dB
• sound wave with an intensity of 100 dB

What is the Doppler Effect

• Where the wavelength of a wave is shifted due to the source moving

• When a wave is shifted when a body pushes the wave

• Where the apparent wavelength of a wave is shifted due to the source moving
