Light is incident on a glass block as shown in figure. If `theta_(1)` is increased slightly, what happens to `theta_(2)`

A ray of light is incident on a parallel-sided glass slab as shown in the figure. The angle of refraction for this ray of light is likely to be :

When a monochromatic light ray is incident on a medium of refracive index mu with angle of incidence theta_(1) ,the angle of refraction is theta_(r). if theta_(i) is changed slightly by Deltatheta_(i) ,then the corresponding change in theta_(r) will be-

A converging beam of light is incident on a right angled isosceles prism as shown in the Figure. The marginal rays in the beam are incident at angle +- theta . The refractive index for the glass of the prism is mu = 1.49 (= (1)/(sin 42°)) . Find the maximum value of theta for which no light comes out of the hypotenuse surface.

Rays of light fall on a glass slab ( mu gtl)as shown in the figure. If mu at A is maximum and at b it is minimum, then what will happen to these rays?

One side of a glass slab is silvered as shown in the figure. A ray of light is incident on the other side at angle of incidence 45^@. Refractive index of glass is given as sqrt2 . The deflection suffered by the ray when it comes out of the slab is

A ray of light is incident on the surface of a glass plate of thickness t . If the angle of incidence theta is small, the emerging ray would be displaced side ways by an amount (Take n = refractive index of glass)
