The displacement of a progressive wave is represented by y = A sin(wt – k x ), where x is distance and t is time. Write the dimensional formula of (i) ω and (ii) k.

Answer :

kvnmurty
y = A sin (w t - k x)
     w = angular velocity =  radians / time        as w t = radians
         = T^-1

   k x = radians  =>  k =  1/x  = L^-1

Answer:

idk

Explanation:

ok so please dont disturb
