A convergent beam is incident on two slabs placed in contact as shownin figure. Where will the rays finally converge?

A converging beam of light rays incident on a glasa-air interface as shown in figure. Find where these rays will meet after refraction.

A convergent beam is incident on a convex mirror. Reflected light

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.

Two identical thin isosceles prisms of refracting angle A and refractive index mu are placed with their bases touching each other and this system can collectively act as a crude converging lens. A parallel beam of light is incident on this system as shown in Figure. Find the focal length of this so called converging lens.

A converging set of ray, traveling from water to air, is incident on a plane interface. In the absence of the interface, the rays would have converged to a point O, 60 cm above the interface. However, dur to refraction the rays will bend. At what distance above the interface will the rays actually converge?

A converging beam of rays in incident on a diverging lens. Having passed through the lens the rays intersect at a point 15 cm from the lens. If the lens is removed, the point where the rays meet, move 5 cm closer to the mounting that holds the lens. Find the focal length of the lens.

Consider a light beam incident from air to a glass slab at Brewster's angle as shown in figure. A polaroid is placed in the path of the emergent ray at point P and rotated about an axis passing through the centre and pependicular to the plane of the plaroid.

Consider a light beam incident from air to a glass slab at Brewster's angle as shown in Figure. A polaroid is placed in the path of the emergent ray at point P and rotated an axis passing through the centre and perpendicular to the plane of the polaroid.

Figure shows a glass sphere of radius 10 cm. along its diameter AB from one side a parallel beam of paraxial rays incident on it. What should be the refractive index of glass so that after refraction all rays will converge at opposite end B.
