Question

A wave generator produces 500 pulses in 10 s. Find the period and frequency of the pulses it produces.​

Answer 1

I got 0.3m

Explanation:

We have that the frequency should be: f=10Hz (number of complete pulses in one second);

having the speed s we can write:

s=fλ

where λ is the wavelength.

We use your data (converting cm to m first getting 300100ms=3ms) and get:

3=10λ

rearranging:

λ=310=0.3m

Answer 2

Explanation:

frequency = 500/10= 50hz

T(time period )= 1/50= 2×10^-2 s
