Two sources of light `0.85` mm apart are illuminated by a light of wavelenths, 6000Å . The phase difference between the two waves intefering on screen,.1.7 m away from the slite at a point 2.5 mm from the central bright band is nearly.

A

13 radians

B

12 radians

C

14 radians

D

11 radians

Text Solution

Verified by Experts

The correct Answer is:
A
Phase diff. `=(2pi)/(lamda)xx"Path diff",=(2pi)/(lamda)xx(xd)/(D)`
=13.08 radians
`=~~13` radians
