Solved: A parallel beam of light enters a glass hemisphere
Chapter 23, Problem 23.77(choose chapter or problem)
A parallel beam of light enters a glass hemisphere perpendicular to the fl at face, as shown in Figure P23.53. The radius of the hemisphere is R _ 6.00 cm, and the index of refraction is n _ 1.560. Determine the point at which the beam is focused. (Assume paraxial rays; i.e., assume all rays are located close to the principal axis.)
