In a Young's double slit experiment using monochromatic light of wavelengths 
, the intensity of light at a point on the screen with a path difference 
is M units and the intensity of light at a point where the path difference is 
is nM units. What is the value of n?
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
0.25
Resultant intensity I R = I 1 +I 2 + 
If path difference, = 
then phase difference 
…. 
=4I=M
If path difference = 
then phase difference 
rad
