Waves Test Review 1 (2024)

Front

What are mechanical waves?

Back

Mechanical waves are disturbances that require a medium (solid, liquid, or gas) to travel through and cannot propagate through a vacuum.

Front

Can mechanical waves travel through empty space?

Back

No, mechanical waves cannot travel through empty space; they need a medium.

Front

What is frequency in the context of waves?

Back

Frequency is the number of cycles of a wave that pass a point in one second, measured in hertz (Hz).

Front

How is wavelength defined?

Back

Wavelength is the distance between successive crests or troughs of a wave.

Front

What does the letter 'A' typically represent in wave diagrams?

Back

The letter 'A' typically represents the wavelength of the wave.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

How do you determine which wave has a greater frequency?

Back

The wave with more cycles per second has a greater frequency.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as frequency increases, wavelength decreases, and vice versa.

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the wave's energy.
