A transverse wave travelling along a stretched string has a speed of 30 ~m / s and a frequency of 250 Hz. The phase difference between two points on the string 10 cm apart at the same instant is

Step-by-step solution

The wavelength of the wave is given by, = v n = 30 250 =0.12 ~m Also, the phase difference ' ' is given by, = 2 path difference aligned & = 2 (0.1) & ...(path difference = & 10 ~cm =0.1 ~m ) & = 2 0.12 0.1 & = ( 5 3 )^ radian aligned
