Front

The SI unit for frequency is ________.

Back

hertz

Front

The highest point on a wave is:

Back

the crest

Front

Which letter(s) represent the crest of the wave?

Back

B & F

Front

The units for frequency are measured in _____________.

Back

hertz

Front

Which of the following can sound travel through?

Back

all of the above

Front

What is a mechanical wave?

Back

A mechanical wave is a disturbance that travels through a medium (solid, liquid, or gas) and requires a medium to propagate.

Front

What is the wavelength of a wave?

Back

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

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 energy of the wave.

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is the formula for wave speed?

Back

Wave speed (v) = frequency (f) × wavelength (λ).
