Question

time period of a wave if 10 waves are produced in 4seconds​

Answer 1

Answer:

To get the wavelength you need to divide 10/4 and you will get answer as 2.5. So the correct wavelength is 2.5

Answer 2

10 wave produced in 4 second

in one minute wave produced= 10/4

=2.5

time period = 1/wave length

= 1/2.5

= 1/25/10

= 10/25

=0.4
