A small air bubble in glass shpere of radius `2 cm` appears to be `1 cm` from the surface when looked at, along a diameter. If the refractive index of glass is `1.5`, find the true position of the air bubble.

A

1.2 cm

B

3.2 cm

C

2.8 cm

D

1.6 cm

Text Solution

Verified by Experts

The correct Answer is:
A
v = 1 cm , R = 2 cm
`(n_(2))/(v) - (n_(1))/(u) = (n_(2) - n_(1))/(R )`
`rArr (1)/(-1) - (1.5)/(u) = (1 - 1.5)/(-2)`
