The _______ of a wave is the number of waves that pass a given point in a certain amount of time.

1

The _______ model of light describes the behavior of light when it acts as a stream of photons.

1

Energy transferred from electromagnetic waves through matter and space is called electromagnetic radiation.

1

The three types of mechanical waves are transverse waves, latitudinal waves, and surface waves.

1

Frequency is measured in units called hertz.
