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:

Options

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 wavve is `alpha//beta`

Answer

B, C, D

Explanation

Here comparing theg iven equation withthe standard equation ofSimple Harmonic Wave `y = A sin(omegat - kx)` we can have option (B),(C), and (D) are correct
