A plane progressive wave is propagating along positive direction of X-axiss where frequency is 100 Hz, amplitude is 20 cm and velocity is 300 m/s. Find the equation of wave.

Explanation

To find the equation of a plane progressive wave propagating along the positive direction of the x-axis, we can follow these steps:

### Step 1: Identify Given Data
- Frequency (f) = 100 Hz
- Amplitude (A) = 20 cm = 0.2 m (convert to meters)
- Velocity (v) = 300 m/s

### Step 2: Calculate the Time Period (T)
