Waves test 2

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points of a wave that are in phase, such as crest to crest or trough to trough.

Front

What is amplitude?

Back

Amplitude is the maximum distance that a point on a wave moves from its rest position. It is related to the energy of the wave.

Front

What is the difference between transparent, translucent, and opaque materials?

Back

Transparent materials allow light to pass through clearly, translucent materials allow some light to pass but not clearly, and opaque materials do not allow light to pass through.

Front

What is an example of a transparent material?

Back

Window glass is an example of a transparent material.

Front

What is an example of an opaque material?

Back

A mirror is an example of an opaque material.

Front

What happens to light when it hits a transparent material?

Back

Light passes through a transparent material without being scattered.

Front

What happens to light when it hits an opaque material?

Back

Light is either absorbed or reflected by an opaque material.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.
