A ray of light wavelength 6xx10^(-5) cm ...

A ray of light wavelength `6xx10^(-5)` cm after passing through two narrow slits, 1mm apart, forms interference fringes on a screen placed 1m away. Find the distance between two successive bright bands of the fringes.

Text Solution

Verified by Experts

Distance between two successive bight bands is the fringe width.
Width of the fringe `y=(D)/(2 d) xx lambda`
Here D =1m , `lambda =6 xx 10^(-5)` cm , 2d = 1 mm =0.1 cm
`:. Y =(100xx6xx10^(-5))/(0.1)`0.06 cm
