JEE Main 2022 Physics question
In Young's double slit experiment performed using a monochromatic light of wavelength , when a glass plate of thickness is introduced in the path of the one of the interfering beams, the intensity at the position where the central maximum occurred previously remains unchanged. The value of x will be:
Answer: (2)
Solution
For the intensity at the old central maximum to remain the same, the extra path difference must be a whole
