Two travelling waves of equal amplitudes and equal frequencies move in opposite directions along a string. They interfere to produce a stationary wave whose equation is given by `(y= 10 cos pi x sin (2pit)/T) cm`.
The amplitude of the particle at `x = 4/3 cm` will be-

Explanation

To find the amplitude of the particle at \( x = \frac{4}{3} \) cm from the stationary wave equation given by

\[ y = 10 \cos(\pi x) \sin\left(\frac{2\pi t}{T}\right) \text{ cm}, \]

we will follow these steps:
