MHT CET 2023 Physics question
In a biprism experiment, monochromatic light of wavelength '' is used. The distance between two coherent sources 'd' is kept constant. If the distance between slit and eyepiece 'D' is varied & and corresponding measured fringe widths are and then
Answer: (B)
Solution
Fringe width in a biprism (or double slit) experiment is . Since and are constant, , i.e. . Therefore $ =
