Waves and Energy

What happens to the frequency of a wave when the energy increases?

• It increases.

• It disappears.

• It remains the same.

• It decreases.

Are you enjoying the video lesson?

• Yes

• No

How is wavelength measured in a wave?

• From the highest point to the lowest point.

• From the crest to the trough.

• From crest to crest or trough to trough.

• From the start of the wave to its end.

What happens to the wavelength as energy decreases?

• It remains constant.

• It disappears.

• It gets longer.

• It gets shorter.

What does amplitude measure in a wave?

• The length of the wave.

• The distance between two crests.

• The height of the wave from the rest position.

• The number of waves passing a point in a second.

If a larger object is dropped into water, how does it affect the waves?

• The wavelength of the waves decreases.

• The frequency of the waves increases.

• The waves become shorter and faster.

• The waves become taller but keep the same frequency and wavelength.
