Question
Two coherent sources of intensities I1 and I2 produce an interference pattern. The maximum intensity in the interference pattern will be : -
Options
A. I1 + I2
B. I12 + I22
C.( I1 + I2)2
D.
Solution
I1 ∝ a12, I2 ∝ a22
Iresultant = I1 + I2 + 2√I1 √I2. cos
Imax = (√I1 + √I2)2, When cos
= 1, 
= 0, 2π.............
Iresultant = I1 + I2 + 2√I1 √I2. cos
Imax = (√I1 + √I2)2, When cos
= 1, = 0, 2π.............Create a free account to view solution
