Find the following for given wave equation.
`P = 0.02 sin [(3000 t - 9 x]` (alll quantities are in `S.I.` units.)
(a) Frequency , (b) Wavelength , (c) Speed of sound wave
(d) If the equilibrium pressure of air is in `10^(5)` Pa then find maximum and minimum pressure.

Explanation

To solve the given wave equation \( P = 0.02 \sin(3000t - 9x) \), we will follow these steps:

### Step 1: Identify the angular frequency (\( \omega \))
From the wave equation, we can see that:
\[ \omega = 3000 \, \text{rad/s} \]
