A simple harmonic progressive wave is represented by y=A (100 t+3 x) . The distance between two points on the wave at a phase difference of 3 radian is

Options

A8 ~m
B9 ~m
C6 ~m
D3 ~m

Correct answer

B. 9 ~m

Step-by-step solution

Equation of the given harmonic progressive wave y=A (100 t+3) General equation of a harmonic wave y = A ( wt + kx ) From equations (i) and (ii), =100 , k =3 But, k = 2 3= 2 = 2 3 We also know, Path difference x = 2 Phase difference x= 2 3 2 3 . ( . Given . = 3 )= 9 ~m
