Waves Test Review

Front

Which color on the visible light spectrum has the least amount of energy?

Back

Red has the least amount of energy in the visible light spectrum.

Front

What is the part of the wave where the particles are close together called?

Back

Compression is the part of the wave where the particles are close together.

Front

What does the wave trough represent in a wave diagram?

Back

The wave trough is represented by the lowest point of the wave.

Front

Which frequency is the lowest: 1,000 Hz, 0.1 Hz, 12,000 Hz, or 20 Hz?

Back

0.1 Hz is the lowest frequency.

Front

What is the part of the wave where the particles are spread out called?

Back

Rarefaction is the part of the wave where the particles are spread out.

Front

Define wavelength in the context of waves.

Back

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

Front

What is amplitude in a wave?

Back

Amplitude is the maximum displacement of points on a wave from its rest position.

Front

Explain the difference between transverse and longitudinal waves.

Back

Transverse waves have oscillations perpendicular to the direction of wave travel, while longitudinal waves have oscillations parallel to the direction of wave travel.

Front

What is the formula for wave speed?

Back

Wave speed = frequency × wavelength.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.
