Consider the figure shown. A system consists of a coaxial glass slab slab (with convex lens of focal length $$f_1$$ inside) and a concave lens of focal length $$f_2$$, separated by a distance $$'d'$$. A parallel beam of light  incident on the glass slab and correspondingly a parallel beam of light emerges out of the concave lom Then the possible correct options are

Consider Fraunhoffer diffraction pattern obtained with a single slit illuminate incidance. At the angular position of the first diffraction minimum in the phase( radian) between the wavelets from the opposite edges of the slit is  

Intensity of the central maximum in Youngs double slit experiment is I. When one of the slit is closed the intensity is $$I_0$$. The ratio $$I / I_0$$ is........

If the frequency of the source is doubled in Young's double slit experiment, then fringe width $$( \beta )$$ will be-

The intensity at the maximum in Young's double slit experiment is $$I_o$$. The distance between two slits is d = 5 $$\lambda$$, where $$\lambda$$ is the wavelength of light used in the experiment. What will be the intensity in front of one of the slits on the screen placed at a distance D = 10d?

What is the effect on the interference fringes in Young's double slit experiment if the source slit is moved closer to the double slit plane?

Through which character we can distnguish the light waves from sound waves.

In YDSE if white is used then.

When an unpolarized light of intensity $$I_0$$ is incident on a polarizing sheet the intensity of the light which does not get transmitted is?

Huygen's theory of secondary waves can be used of find-
