MHT CET 2025 Physics question
In Young's double slit experiment, the distance between the slits is 2mm and the slits are 1 m away, from the screen. Two interference patterns can be obtained on the screen due to light of wavelength '' and '' respectively. The separation on the screen between the order bright fringes on the two interference patterns is ( = 1.5 )
Answer: (A)
Solution
The position of the th bright fringe is . For the separation is \dfrac{3D}{d}\dfrac{3× 1}{2×10^{-3}}$(1.5λ_1 - λ_1) = 1500×
