Distance of 5th dark fringe from centre is $$4 \mathrm{~mm}$$. If $$D=2 \mathrm{~m}, \lambda=600 \mathrm{~nm}$$, then distance between slits is

A light of wavelength $$500 \mathrm{~nm}$$ is incident on a Young's double slit. The distance between slit and screen is $$D=1.8 \mathrm{~m}$$ and dis...

Assertion : Distance between position of bright and dark fringe remain same in YDSE. Reason : Fringe width, $$\beta=\frac{\lambda D}{d}$$...

Assertion : Incoming light reflected by earth is partially polarised. Reason : Atmospheric particle polarise the light.

An unpolarised beam of intensity $$2 a^2$$ passes through a thin polaroid. Assuming zero absorption in the polaroid, the intensity of emergent plane p...

Red light of wavelength 5400 $$\mathop A\limits^o $$ from a distant source falls on a slit 0.80 mm wide. Calculate the distance between first two dark...

Assertion : If a glass slab is placed in front of one of the slits, then fringe with will decrease. Reason : Glass slab will produce an additional pat...
