Question

How often a wave occurs (repeats its back and forth or up and down motion) is the wave's _____________. *

-crest
-frequency
-wavelength
-resting point

Answer 1

Frequency

Step-by-step explanation:

The number of times a wave is occurring is called the frequency of a wave. It is also defined as the number of vibrations or oscillations per unit time. It is represented by f or
`\\u` (nu).

Its relation with the wavelength and the speed of a wave is given by :

`\\u =(v)/(\lambda)`

Hence, we can say that the correct option is (B) "frequency"
