The speed of a wave in a stretched string is `20ms^(-1)` and its frequency is 50Hz. Calculate the phase difference in radian between two points situated at a distance of 5 cm on the string ?

Explanation

To solve the problem, we need to calculate the phase difference in radians between two points on a stretched string that are separated by a distance of 5 cm. We will use the formula for phase difference, which is given by:

\[ \Delta \phi = \frac{2\pi}{\lambda} \Delta x \]
