Front

What do you need to calculate wave speed?

Back

Frequency and wavelength.

Front

What is a disturbance that transfers energy from one place to another?

Back

Wave.

Front

What is the wave property that tells you how long it takes for the wave to repeat?

Back

Wave period.

Front

What affects the energy of a wave?

Back

The amplitude or frequency, energy loss to a medium, and energy loss due to spreading.

Front

True or False: Waves travel faster in solids than in liquids and faster in liquids than in gases.

Back

True.

Front

What is the definition of frequency?

Back

The number of cycles of a wave that occur in a unit of time.

Front

What is wavelength?

Back

The distance between two consecutive points of the same phase on a wave.

Front

What is amplitude?

Back

The maximum displacement of points on a wave from its rest position.

Front

What is the relationship between frequency and wave period?

Back

Frequency is the inverse of wave period; as frequency increases, wave period decreases.

Front

What is a medium in the context of waves?

Back

The substance through which a wave travels.
