JEE Main 2012 Physics question
In a Young's double slit experiment with light of wavelength λ, fringe pattern on the screen has fringe width β. When two thin transparent glass (refractive index μ ) plates of thickness and are placed in the path of the two beams respectively, the fringe pattern will shift by a distance
Answer: (3)
Solution
A plate of thickness t adds optical path . The net extra path difference is , and a path
