A transparent sphere of unknown composition is observed to form an image of the Sun on the surface of the sphere opposite the Sun. What is the refractive index of the sphere material?
Added by Alan P.
Step 1
Step 1: Apply the formula for a single reflection on a reflecting surface, where we have object distance (u) as infinite (since the Sun is at an infinite distance from the sphere), image distance (v) as 2r (twice the radius of the sphere), refractive index of the Show more…

Parallel light rays enter a transparent sphere along a line passing through the center of the sphere. The rays come to a focus on the far surface of the sphere. What is the sphere's index of refraction?
Using a block of a transparent, unknown material, it is found that a beam of light inside the material is totally internally reflected at the air-block interface at an angle of $48.0^{\circ} .$ What is its index of refraction?
