Question

The displacement of a pressure wave is represented by y=ASin (wt-kx), where x is distance and T is time. Write the dimensional formula of (i)w and (ii) k.

Answer 1

The displacement of a progressive wave is represented by y = A sin(wt – k x ) ... Write the dimensional formula of (i) ω and (ii) k. ... w = angular velocity = radians / time as w t
