A ray of light AO is incident on a diverging lens as shown in figure. The focal plane of the lens is also given. The possible direction of the refracted ray will be

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 :

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

From the ray diagram shown in Fig. calculte the focal length of concave lens. .

Converging light rays are falling on a convex lens. If the focal length of the lens is 30 cm, then find the position of the image.

A parallel beam of rays is incident on a convergent lens with a focal length of 40 cm. Where should a divergent lens with a focal length of 15 cm be placed for the beam of rays to remain parallel after passing through the two lenses.

A converging beam of rays is 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.

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

A ray of light AO is vacuum is incident on a glass slab at angle 60^@ and refracted at angle 30^@ along OB as shown in the figure.The optical path light ray from A to B is :
