A ray of light on a transparent sphere with centre C as shown in the figure. The ray emerges from sphere parallel to line AB. The refractive index of sphere is

A

`sqrt(2)`

B

`sqrt(3)`

C

`(3)/(sqrt(2))`

D

2

Text Solution

Verified by Experts

The correct Answer is:
B

In diagram angle of emergence `= 60^(@)`
`:. angle BOC = 60^(@)`
`:. r+ r = 60^(@) rArr r = 30^(@)`
`:. Mu = (sin 60^(@))/(sin 30^(@)) rArr mu = sqrt(3)`

A spider is hanging by means of its own silk thread directly above a transparent fixed sphere of radius R=20cm as shown in the figure. The refractive index of the material of the sphere is equal to sqrt(2) and the height of the spider from the centre of the sphere is 2R(=40cm) . An insect, initially sitting at the bottom, starts crawling on the sphere along a vertical circular path with the constant speed of pi//4 cm//s . For how long time the insect will be invisible for the spider, assume that it crawls once round the vertical circle.
