Width of two slits in Young's double slits experiment are in the ratio 9:4.
The ratio of the amplitudes of light waves through them would be:
- A 2 : 1
- B 4 :9
- C 2 : 3
- D 3 : 2
Answer & Solution
Correct Answer
(D) 3 : 2
Step-by-step Solution
Detailed explanation
\( \frac{A_1}{A_2} = \sqrt{\frac{w_1}{w_2}} \) \( \frac{A_1}{A_2} = \sqrt{\frac{9}{4}} = \frac{3}{2} \)
