Question

ABCD represent a convex lens, draw the emergent rays.

Answer 1

Answer:

(a) The labelled diagram is shown.

(b) The refractive index of diamond is 2.42. Refractive index of diamond is the ratio of the speed of light in air to the speed of light in diamond.i.e.,

μ=

Speedoflightindiamond

Speedoflightinair

and, the ratio of these velocities is 2.42. i.e., This means that the speed of light in diamond will reduce by a factor of 2.42 as compared to its speed in air. In other words, the speed of light in diamond is

2.42

1

times the speed of light in vacuum.

Answer 2

i is the angle of incidence and e is the angle of emergence . i = e and r1 = r2 So, the incident ray and the emergent ray are parallel

i is the angle of incidence and e is the angle of emergence . i = e and r1 = r2 So, the incident ray and the emergent ray are parallel followme
