The equation of a wave is given by `Y = 5 sin 10pi(t - 0.01x)` along the x-axis. (All the quantities are expressed in SI units). The phase difference between the points separated by a distance of `10 m` along x-axis is

Options

A. `pi/2`
B. `pi`
C. `2pi`
D. `pi/4`

Answer

B

Explanation

`K=10pi(0.01)=0.1pi=(2pi)/(lamda), Deltaphi=K` (path differnece)=0.1`pi(10)=pi`.
