MHT CET 2025 Physics question
In Young's double slit experiment, in an interference pattern, a minimum is observed exactly in front of one slit. The distance between the two coherent sources is d and D is the distance between sources and screen. The possible wavelength used are proportional to
Answer: (B)
Solution
Take the origin midway between the slits; the slits are at . A point directly in front of one slit is at . The path difference there is . For a minimum, with , so
