Question

What is the frequency of the waves and what is its period when source produces 15 waves in 3 seconds

Answer 1

Given :

No. of oscillations = 15

Time = 3 sec

To find :

Frequency

Answer:

Frequency of a wave (as sound wave) is defined as the number of oscillations per second.

i.e.

f = no. of oscillations / time (in second)

So,

f = 15 / 3

f = 5 Hz
