The phase difference corresponding to path difference of $x$ is

A

$\frac {2\pi x}{\lambda }$

B

$\frac {2\pi \lambda }{x}$

C

$\frac {\pi x }{\lambda }$

D

$\frac {\pi \lambda }{x}$

Solution

$\frac{{\Delta \phi }}{{2\pi }} = \frac{{\Delta x}}{\lambda }$ ${\{ \,\,\Delta x\, = \,x\,\} }$

$\boxed{\Delta \phi = \frac{{2\pi x}}{\lambda }}$
