XL Unit 7 Science Review

Front

What are translucent materials?

Back

Translucent materials allow some light to pass through partially, but not in a straight path.

Front

Give an example of a transverse wave.

Back

Light is an example of a transverse wave.

Front

What is the wavelength of a wave?

Back

The wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What does it mean when some light passes through?

Back

It means the material is translucent.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is amplitude in a wave?

Back

Amplitude is the height of the wave from its rest position to the crest.
