JEE Main 2022 Physics question
In a Young's double slit experiment, a laser light of 560 nm produces an interference pattern with consecutive bright fringes' separation of 7.2 mm. Now another light is used to produce an interference pattern with consecutive bright fringes' separation of 8.1 mm. The wavelength of second light is nm.
Answer: 630
Solution
The fringe width is , so $β _{1}/β _{2} =
