MHT CET 2023 Physics question
Two sources of light 0.6 mm apart and screen is placed at a distance of 1.2 m from them. A light of wavelength 6000 A used. Then the phase difference between the two light waves interfering on the screen at a point a distance 3 mm from central bright band is
Answer: (D)
Solution
Path difference at a point from the central maximum: m. Wavelength m, so $Δ
