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...

An interference pattern is observed by Young’s double slit experiment. If now the separation between coherent source is halved and the distance of scr...

A tube of sugar solution $$20 \mathrm{~cm}$$ long is placed between crossed nicols and illuminated with light of wavelength $$6 \times 10^{-5} \mathrm...

In the given figure, $$C$$ is middle point of line $$S_1 S_2$$. A monochromatic light of wavelength $$\lambda$$ is incident on slits. The ratio of int...

The Young's double slit experiment is performed with blue and green light of wavelengths 4360 Å and 5460 Å respectively. If $$x$$ is the distance of 4...

Assertion : Corpuscular theory fails in explaining the velocities of light in air and water. Reason : According to corpuscular theory is that light sh...
