Roopa conducts an experiment with light. She notices that when light rays fall on the surface of a certain object, the light rays change direction. When the light leaves the object from another surface, the light rays bend again. (a) What could be the object that Roopa used to conduct this experiment? (b) Why does the light bend twice? Explain with two points.
