How would you express the frequency of a wave in which five peaks passed a given point each second? explain your answer.

n = number of peaks passed a particular point = 5

t = time taken by the peaks to pass a particular point = 1 sec

f = frequency of the wave

by definition , frequency is the repetition of an event in a given interval of time.

we know that frequency is given as

f = n/t

inserting the values

f = 5/1

f = 5 Hz

hence the frequency of the wave comes out to be 5 Hz

the answer is option a.
