Question

Example 8.1 A WAVE GENERATOR A wave generator produces 500 pulses in 10 s. Find the period and frequency of the pulses it produces.​

Answer 1

Answer:

I got

0.3

m

Explanation:

We have that the frequency should be:

f

=

10

H

z

(number of complete pulses in one second);

having the speed

s

we can write:

s

=

f

λ

where

λ

is the wavelength.

We use your data (converting cm to m first getting

300

100

m

s

=

3

m

s

) and get:

3

=

10

λ

rearranging:

λ

=

3

10

=

0.3

m
