Question

Which describes the frequency for a wave?

A. the amount of time it takes the wave to stop vibrating

B. the amount of time that passes between crests of a wave

C. the number of wave cycles that pass a point in a given time

D. the measurement from crest to trough

Answer 1

Hi! the answer is C

Answer 2

Option C

Step-by-step explanation:

The frequency of a wave is defined as the number of wave cycles completed in one second.

It is denoted by f and the SI unit of frequency is Hertz(Hz) or cycles per second.

The time period of a wave is defined as the time taken by the wave to complete one vibration or one wave cycle.

It is denoted by T and its SI unit is second.

The relation between frequency and time period is given by

frequency =
`(1)/(Time period)`
