Question
A plane progressive wave of frequency 25 Hz, amplitude 2.5 × 10-5 m and initial phase zero moves along the negative x-direction with a velocity of 300 m/s. A and B are two points 6m apart on the line of propagation of the wave. At any instant the phase difference between A and B is φ. The maximum difference in the displacements of particle at A and B is ᐃ.
Options
A.φ = π
B.φ = 0
C.ᐃ = 0
D.ᐃ = 5 × 10-5 m
Solution
= 12m.Separation between A and B = 6 m = λ/2
