A stationary wave is formed by superposition of two constituent waves, having amplitude, frequency and velocity as 10 cm, 40 Hz and 200 cm/s, respectively. Write the equation of the stationary wave.

Explanation

To find the equation of the stationary wave formed by the superposition of two constituent waves, we can follow these steps:

### Step 1: Determine the Time Period (T)
The time period \( T \) can be calculated using the formula:
\[ T = \frac{1}{f} \]
where \( f \) is the frequency. Given \( f = 40 \, \text{Hz} \):
