Given that

{y}={A} \sin ({aEt}-{bVx})

where

{y}

displacement,

{E}

energy,

{V}

is velocity,

{t}

and

{x}

are time and distance respectively then, the dimension of

{a / b}

is:

View answer and explanation

Correct option: C

{M}^{-1} {L}^0 {T}^0

Option C is correct because by equating the dimensions of the arguments of the sine function, we can find the dimensions of a/b as M⁻¹L⁰T⁰.
