How will the interference pattern in Young's double-slit experiment be affected if the screen is moved away from the plane of the slits?

उत्तर
Fringe width = β = `"Dλ"/"d"`
As D increases, the fringe width increases.

A beam of light consisting of two wavelengths 600 nm and 500 nm is used in Young's double slit experiment. The silt separation is 1.0 mm and the screen is kept 0.60 m away from the plane of the slits. Calculate:
