A parallel beam of light travelling in water (refractive index ` =4//3)` is refracted by a spherical air bublle of radius 2mm situated in water. Assuming the light rays to be paraxial,
a. Find the position of image due to refraction at first surface and position of the final image.
b. Draw a ray diagram showing the position of both images.

Answer

`-6` mm from I surface, -5mm from `2^(nd)` surface
