The type of energy transferred by a wave in a medium is energy

kinetic

When sound waves interfere to create standing waves the points on the medium that move up and down with the largest amplitudes are called nodes

False

When a wave moves from a dense medium to a less dense medium most of the wave energy is

refracted

Sound waves are longitudinal mechanical compression waves

A. True

The pitch of a sound is determined by its and speed together or its frequency alone

The pitch of a sound can be determined by its frequency alone.

For a stationary observer when the source of a sound is moving its pitch appears to change
