In Young's double slit experiment, when light of wavelength 600 nm is used, 18 fringes are observed on the screen. If the wavelength of light is changed to 400 nm , the number of fringes observed on the screen is
- A \(27\)
- B \(18\)
- C \(22\)
- D \(24\)
Answer & Solution
Correct Answer
(A) \(27\)
Step-by-step Solution
Detailed explanation
\(N_1 \lambda_1 = N_2 \lambda_2\) \(N_2 = \frac{N_1 \lambda_1}{\lambda_2}\)
