The displacement of a particle in a medi...

The displacement of a particle in a medium due to a wave travelling in the `x-`direction through the medium is given by `y = A sin(alphat - betax)`, where `t =` time, and `alpha` and `beta` are constants:

A

the frequency of the wave is `alpha`

B

the frequency of the wave is `alpha//2pi`

C

the wavelength is `2pi//beta`

D

the velocity of the wave is `alpha//beta`

Text Solution

Verified by Experts

The correct Answer is:
