A point like light source is placed to the symmetry axis of a hemisphere shaped piece of glass of radius 20 cm 10 cm away from the plane surface The refractive index of glass is 1 5 A ray of light whose angle of incidence is 60 is incident as show in the diagram After coming out of amisphere ray of light will again cut the symmetry axis at some point Find out distance between source and that point 60 10 cm 20 cm
