A parallel beam of light travelling in water (refractive index=43) is – InterviewSolution

1.	A parallel beam of light travelling in water (refractive index=43) is refracted by a spherical air bubble of radius 2 mm situated in water. Assuming the light rays to be paraxial. Find the distance (in mm) between position of the image due to refraction at the first surface and the position of the final image
Answer» A parallel beam of light travelling in water (refractive index $= \frac{4}{3}$ ) is refracted by a spherical air bubble of radius $2 mm$ situated in water. Assuming the light rays to be paraxial. Find the distance ( $in mm$ ) between position of the image due to refraction at the first surface and the position of the final image
