Question

The equation of a progressive wave is `y = 0.4 sin 2pi [(t)/(0.02) - (x)/(60)]`, where x is in cm. Thenn the phase difference between two points separated by 6 cm at any instant is
A. `pi`
B. `pi//3`
C. `pi//2`
D. `pi//5`

Answer 1

Correct Answer - D
`delta = (2pi x)/(lamda) = (2pi xx 6)/(60) = (pi)/(5)`
