A plastic hemisphere has a radius of curvature of 8cm and an index of refraction of 1.6. On the axis halfway between the plane surface and the spherical one (4cm from each) is a small object O.  The distance between the two images when viewed  along the axis from the two sides of the hemisphere is approximately.  img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BMS_V04_C01_E01_173_Q01.png" width="80%"
