Question

A wave oscillates with a period of 4.25 X 10-10 s. How many waves will strike a signal detector in 3 seconds?

Answer 1

waves

Step-by-step explanation:

Given that,

A wave oscillates with a period of

We need to find the number of waves that will strike a signal detector in 3 seconds.

We know that,

Frequency = (no. of oscillations)/time

Time period = time/(no. of oscillations)

Let there are n waves that will strike

So,

Hence,
waves will strike in 3 seconds.
