Waves Unit Review

Front

What is a medium in the context of waves?

Back

A medium is a substance or material through which a wave travels, such as air, water, or solid materials.

Front

What are mechanical waves?

Back

Mechanical waves are waves that require a medium to travel through, such as sound waves and water waves.

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.

Front

What type of wave is light?

Back

Light is a transverse wave.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the motion of the medium is perpendicular to the direction of the wave's travel.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the motion of the medium is parallel to the direction of the wave's travel.

Front

What is the amplitude of a wave?

Back

The amplitude is the maximum distance that the particles of the medium move from their rest position.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is wavelength?

Back

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

Front

Can sound travel in outer space? Why or why not?

Back

No, sound cannot travel in outer space because there is no medium (like air) for the sound waves to travel through.
