For a progressive wave propagating along positive X-direction, amplitude, frequency and velocity are 10 cm, 300 Hz and 440 m/s, respectively. Write the equation of the wave.

Explanation

To write the equation of a progressive wave propagating along the positive x-direction, we follow these steps:

### Step 1: Identify the given parameters
- Amplitude (A) = 10 cm = 0.10 m (convert to meters)
- Frequency (f) = 300 Hz
- Velocity (v) = 440 m/s

### Step 2: Calculate the wavelength (λ)
