If the intensities of the two interfering beams in Young's double slit experiment be I1 and I2, then the contrast between the maximum and minimum intensity is good when –
A
I1 is much greater than I2
B
I1 is much smaller than I2
C
Either I1 or I2 is zero
D
I1 = I2
Answer
I1 = I2
Explanation
Solution
For good visibility condition is
Imin = 0 ̃ I1=I2
