The ratio of intensities of two waves producing interference is 9: 4 , then the ratio of the resultant maximum and minimum intensities will be ( 3 = 1 2 )
Options
- A4: 9
- B9: 4
- C25: 1
- D5: 1
Correct answer
C. 25: 1
Step-by-step solution
I₁ I₂ = 9 4 a₁ a₂ = 3 2 a₁+a₂ a₁-a₂ = 3+2 3-2 = 5 1 (a₁+a₂ )² (a₁-a₂ )² = 25 1
