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) gt R_(B)`

B

`R_(B) gt R_(A)`

C

`R_(A) = R_(B)`

D

Information is not suficient to decide.

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
implies `slope B gt slope A`
hence `R_(A) gtR_(B)`

A sinusoidal wave is propagating along a streched string that lies along the x-axis. The displacement of the string as a function of time is graphed in for particles at x-0 and at x=0.0900 m. (a) what is the amplitude of the wave? (b)what is the period of the wave? (c ) you are told that the two points x=0 and x=0.0900 m are within one wavelength of each other. if the wave is moving in the +x-direction, determine the wavelength and the wave speed. (d) if instead the wave is moving in the -x-direction, determine the wavelength and the wave speed. (e) would it be possible to derermine definitely the wavelength in parts (c ) and (d) if you were not told that the two points were within one wavelength of each other? why ot why not?
