Small amplitude progressive wave in a stretched string has a speed of 100 cms ⁻¹ , and frequency 100 ~Hz . The phase difference between two points 2.75 ~cm apart on the string, in radians, is

Step-by-step solution

aligned & Given; f =100 ~Hz , v =100 ~cm ~s ⁻¹=1 ~ms ⁻¹, & x =2.75 ~cm =2.75 10⁻² ~m , Phase difference & =? & = 2 x = 2 v f x [ v = f ] & or, = 2 2.75 10⁻² 1 100= 11 2 aligned
