In a wave, the path difference corresponding to a phase difference of `phi` is

Options

A. (a) `(pi)/(2lambda)varphi`
B. (b) `pi/lambdavarphi`
C. (c) `(lambda)/(2pi)varphi`
D. (d) `(lambda)/(pi)varphi`

Answer

C

Explanation

For `2pi` phase difference `rarr` Path difference is `lambda`
`:.` For `phi` phase difference `rarr` Path difference is `(lambda)/(2pi)xxvarphi`
