Waves, Light, and Sound Practice Test 2024

Front

What is a wave?

Back

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

Front

What are the two main types of waves?

Back

Transverse waves and longitudinal waves.

Front

What is the wavelength of a wave?

Back

The distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

Front

Which color of light has the longest wavelength?

Back

Red light has the longest wavelength.

Front

What type of lens is used to converge light rays?

Back

A convex lens.

Front

What type of lens is used to diverge light rays?

Back

A concave lens.

Front

What is a transverse wave?

Back

A wave in which the particles of the medium move perpendicular to the direction of the wave's travel.

Front

What is a longitudinal wave?

Back

A wave in which the particles of the medium move parallel to the direction of the wave's travel.

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

How does frequency relate to pitch in sound?

Back

Higher frequency sounds have a higher pitch, while lower frequency sounds have a lower pitch.
