Physical Science - Waves Quiz

What is the term for the measure of how far a wave travels in a given amount of time?

• Wave Speed

• Wave Frequency

• Wave Amplitude

• Wave Length

What is the unit of frequency?

• Decibel (dB)

• Hertz (Hz)

• Newton (N)

• Joule (J)

What is the term for the highest point of a wave?

• Trough

• Crest

• Wave Base

• Amplitude

What is the relationship between frequency and wavelength in a wave?

• As frequency increases, wavelength decreases.

• As frequency increases, wavelength increases.

• Frequency and wavelength are unrelated.

• Frequency is inversely proportional to amplitude.

What happens to the frequency of a wave when the wavelength decreases, assuming wave speed remains constant?

• Frequency decreases.

• Frequency remains the same.

• Frequency increases.

• Frequency becomes zero.

What is the term for the area in a longitudinal wave where particles are close together?

• Compression

• Rarefaction

• Amplitude

• Wavelength

What is the phenomenon called when a wave changes direction as it passes from one medium to another?

• Reflection

• Refraction

• Diffraction

• Absorption

What is the term for the amount of energy a wave carries, often measured from the mid-line to the crest or trough?

• Frequency

• Amplitude

• Velocity

What is the term for the lowest point of a wave?

• Crest

• Trough

• Peak

• Waveform

What is the term for the bouncing back of a wave when it hits a barrier?

• Refraction

• Diffraction

• Reflection

• Absorption
