A ball is kept at a height h above the surface of a heavy transparent sphere made of a material of refractive index mu. The radius of the sphere is R. Aț.t = 0, the ball is dropped to fall normally on the sphere. For t lt sqrt((2h)/(g))and by a single refraction, what is the speed of image as a function of time ? |
