Two coherent sources of intensity ratio 9: 4 produce interference. The intensity ratio of maxima and minima of the interference pattern is
Options
- A13:6
- B5:1
- C25:1
- D3:2
Correct answer
C. 25:1
Step-by-step solution
aligned & I_ I_ = ( I₁ + I₂ I₁ - I₂ )^2= ( 9 + 4 9 - 4 )^2 & = ( 3+2 3-2 )^2=25 aligned
