In a stretched string, the speed of a wave is 25 m/s and its frequency is 60 Hz. Determine the phase difference in radian between two points situated at a disatance of 8 cm on the string.

Explanation

To determine the phase difference between two points situated at a distance of 8 cm on a stretched string where the speed of the wave is 25 m/s and its frequency is 60 Hz, we can follow these steps:

### Step 1: Convert the distance from cm to meters
Given distance \( \Delta x = 8 \, \text{cm} \), we need to convert this to meters.
\[ \Delta x = 8 \, \text{cm} = 0.08 \, \text{m} \]
