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

kinetic

A trough in a transverse wave corresponds to a in a longitudinal wave

rarefaction

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

In a fixed medium what can contribute to a higher pitched sound

Higher wave speed and shorter wavelength can each contribute to a sound of higher pitch.

On the decibel scale an increase of decibels means an intensity increase ten times

ten

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

refracted

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

true

The amount of diffraction that occurs when a sound wave encounters a barrier depends on the waves

wavelength

green

What All of the visible color light waves together result in light

White light
