Find critical angle of incidence for light that is trapped

Reference no: EM13542395

A flash light is at the bottom of a 2m deep pool.

a) Find the critical angle of incidence for the light that is trapped or reflected back
b) The light that escapes the pool form a round illuminating circle at the surface. Find its radius. ( Hint: Use the information in part (a), as well as the fact that the flash lamp is two meters from the surface to answer this question using trigonometric formulas) ?
