Answer to Question #206712 in Optics for sonu

Question

In Young's double slit experiment, the phase

difference between two interfering beams is

(pi/2). If the wavelength of light is 580 nm,

calculate the path difference between the

interfering beams.

Answer 1

$\Delta=\frac{2\pi \delta}{\lambda}=\frac{2}{\pi}.$
