In YDSE, if a bichromatic light having wavelengths `lambda_(1)` and `lambda_(2)` is used, then maxima due to both lights will overlaps at a certain distance y from the central maxima. Take separation between slits as d and distance between screen and slits as D. Then the value of y will be

In a Young's double-slit experiment, if the incident light consists of two wavelengths lambda_(1) and lambda_(2) , the slit separation is d, and the distance between the slit and the screen is D, the maxima due to each wavelength will coincide at a distance from the central maxima, given by

In a Young's double slit experiment, one of the slits is covered by a thin film of thickness t=0.04 mm, and refractive index mu=1.2+(9xx10^(-14)m^(2))/(lambda^(2)) , where lambda is the wavelength in meter. A beam of light consisting of two wavelength lambda_(1)=400nm and lambda_(2)=600 nm falls normally on the plane of the slits. Find the distance between two central maxima in milimeter. Distance of screen from slits is 400 times the the separation between the slits.
