If a torch is used in place of monochromatic light in Young's experiment what will happen?

A

Fringe will occure as from monochromatic source

B

Fringe will appear for a moment and then it will disappear

C

No fringe will appear

D

Only bright fringe

Text Solution

Verified by Experts

The correct Answer is:
C
Light waves emitted from torch are of different wavelenghts hence interference pattern will not be observed.

A parallel beam of monochromatic light is used in a Young's double slit experiment. The slits are separated by a distance d and the screen is placed parallel to the plane of the slits. Show that if the incident beam makes an angle theta=sin^-1(lamda/(2d)) with the normal to the plane of the slits, there will be a dark fringe at the centre Po of the pattern.
