MHT CET 2024 Physics question
A screen is placed at 50 cm from a single slit, which is illuminated with light of wavelength 600 nm. If separation between the 1 and 3 minima in the diffraction pattern is 3mm then slit width is
Answer: (A)
Solution
In single slit diffraction the th minimum lies at . The separation between the 1st and 3rd minima is m. So \dfrac{2λ D}{3×10^{-3}}$ =
