The displacement of a progressive wave is represented by `y = A sin (omegat - kx),` where x is distance and t is time. Write the dimensional formula of (i) `omega` and (ii) k.

Explanation

To find the dimensional formulas for \( \omega \) and \( k \) from the wave equation \( y = A \sin(\omega t - kx) \), we will follow these steps:

### Step-by-Step Solution:

1. **Understanding the Wave Equation**:
The wave equation is given as \( y = A \sin(\omega t - kx) \). Here, \( y \) is the displacement, \( A \) is the amplitude, \( \omega \) is the angular frequency, \( k \) is the wave number, \( t \) is time, and \( x \) is distance.
