In a Young's double slit experiment, \(m\) th order and \(n\)th order of bright fringes are formed at point \(P\) on a distant screen, if monochromatic source of wavelength \(400 \mathrm{~nm}\) and \(600 \mathrm{~nm}\) are used respectively. The minimum value of \(m\) and \(n\) are respectively,
- A 4,6
- B 3,2
- C 2,3
- D 4,2
Answer & Solution
Correct Answer
(B) 3,2
Step-by-step Solution
Detailed explanation
Let \(m^{\text {th }}\) bright fringe of wavelength \(\lambda_{r \pi}\) and \(n^{\text {th }}\) bright fringe of wave length \(\lambda_n\) formed at a distance \(x_n\) from central maxima at same point \(P\), i.e., they coincide, therefore, \(x_n=x_n\).…
