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

Answer:

Frequency

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 $\nu$ (nu).

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

$\nu =\dfrac{v}{\lambda}$

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