Under what condition, maximum particle velocity is four times the wave velocity corresponding to the equation,
`y=A sin(omegat-kx)`

Explanation

To solve the problem, we need to find the condition under which the maximum particle velocity is four times the wave velocity for the wave described by the equation \( y = A \sin(\omega t - kx) \).

### Step-by-Step Solution:

1. **Identify the maximum particle velocity**:
The maximum particle velocity (\( v_p \)) for a wave can be expressed as:
\[
v_p = \omega A
