Question

The equation of a wave is given by (all quantity expressed in S.I units) `y=5sin10pi(t-0.01x)` along the x-axis. The magnitude of phase difference between the points separated by a distance of 10 m along x-axis is
A. `pi//2`
B. `pi`
C. `2pi`
D. `pi//4`

Answer 1

Correct Answer - B
The magnitude of phase difference between the points separated by distance 10 meters `=kxx10=[10 pixx0.01]xx10=pi`
