A wave pulse is generated in a string that lies along `x-`axis. At the points `A` and `B`, as shown in figure, if `R_(A)` and `R_(B)` are ratio of magnitudes of wave speed to the particle speed, then

A

`R_(A)gtR_(B)`

B

`R_(B)gtR_(A)`

C

`R_(B)=R_(A)`

D

information is not sufficient

Text Solution

Verified by Experts

The correct Answer is:
a
Slope at any point on the string in wave motion represents the ratio of particle speed to wave speed. Therefore, slope Bltslope A
Hence `R_(A)gtR_(B)`.
