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

2

Explanation

`K=0.01 xx 10`pi`
K=(10)/(100) pi = (2pi)/(lambda)`
`lambda = 20`
`phi=(2pi)/(lambda)(x)=(2pi)/(lambda)(10)=(2pixx10)/(20) =pi`
`phi =pi`
