Waves and Energy Practice

Front

What is the wavelength of an infrared ray?

Back

10^-5 m

Front

What happens to the frequency of a wave when the amplitude is tripled?

Back

Amplitude does not affect frequency.

Front

Which wave has the greatest frequency in a diagram?

Back

Wave 4.

Front

What do longitudinal waves have?

Back

Compressions and rarefactions.

Front

What is a wave that needs a medium to travel called?

Back

Mechanical wave.

Front

Define wavelength.

Back

The distance between successive crests of a wave.

Front

What is frequency?

Back

The number of waves that pass a point in one second.

Front

What is amplitude?

Back

The maximum extent of a wave's displacement from its rest position.

Front

What are electromagnetic waves?

Back

Waves that can travel through a vacuum and do not require a medium.

Front

What is the relationship between frequency and wavelength?

Back

They are inversely related; as frequency increases, wavelength decreases.
