The phase difference between two points seperated by 0.8 m in wave of frequency is 120 Hz is . The velocity of the wave is
720 m/s
384 m/s
250 m/s
1 m/s
Phase difference =
velocity v = n = 120 X 3.2 = 384 m/s
In phase and out of phase -
i.e. point seprated by distance are in same phase.
Point separated by are out of phase.
