The ratio of the distance of \(\mathrm{n}^{\text {th }}\) bright band and \(\mathrm{m}^{\text {th }}\) dark band from the central bright band in an interference pattern is
- A n: m
- B m: n
- C \(n:\left(m-\frac{1}{2}\right)\)
- D \(\left(n-\frac{1}{2}\right): m\)
Answer & Solution
Correct Answer
(C) \(n:\left(m-\frac{1}{2}\right)\)
Step-by-step Solution
Detailed explanation
\(y_{\text{bright}} = \frac{n\lambda D}{d}\) \(y_{\text{dark}} = \frac{(m - \frac{1}{2})\lambda D}{d}\)
