Three waves, all having the same amplitude and wavelength, travel along a string in the same direction. One of the wave has phase constant of 45°. The phase constants of the other waves, if all three together produce fully destructive interference, are:
Text Solution
Verified by ExpertsThe correct answer is:
C
For fully destructive interference all waves must have phase difference of 120 0 with respect to each other. Thus phase constants are (45 0 + 120 0 ) and (45 0 + 240 0 ).
