A plate of thickness t is made up of a material of refractive index μ – InterviewSolution

1.	A plate of thickness t is made up of a material of refractive index μ. It is placed in front of one of the slits, in a double-slit experiment. What should be the minimum thickness t of the plate, which will make the intensity at the center of the fringe pattern zero ?
Answer» A plate of thickness $t$ is made up of a material of refractive index $μ$ . It is placed in front of one of the slits, in a double-slit experiment. What should be the minimum thickness $t$ of the plate, which will make the intensity at the center of the fringe pattern zero ?
