Question

(3) 5 mm
(4) 1 mm
A beam of light consisting of two wavelengths,
650 nm and 520 nm is used to obtain
interference in YDSE. If bright fringes due to
both the wavelengths concide at any point P
then least distance of P from central maxima is
(Slit separation is 2 mm and distance between
slits and screen is 1.2 m)
(1) 1.56 mm
(2) 2.36 mm
(3) 3 mm
(4) 1.8 mm
In single SIIL
le slit diffraction experiment, if slit width is
hin of original then intensity increases​
