Figure shows the shape of part of a long string in which transverse waves are produced by attaching one end of the string to tuning fork of frequency 250 Hz. What is the velocity of the waves?

A

`1.0m s^(-1)`

B

`1.5ms^(-1)`

C

`2.0ms^(-1)`

D

`2.5ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
It is clear from the figure that the wavelength `lambda=0.4cm`. Now `upsilon=250Hz`
`therefore v=upsilonlambda=250xx0.4=100 cms^(-1)=1ms^(-1)`
