1. The problem statement, all variables and given/known data Travellers in hot places often think that they see water in the distance, when there is nothing but land there. This effect is called a mirage. The air near the ground is very hot, and light reflects off the top of this layer of hot air. The diagram below shows how you could demonstrate the effect in a laboratory. On the diagram, draw appropriate normals and mark: An angle of incidence, labelled I, An angle of refraction, labelled R, and An angle labelled G which you know is greater than the critical angle. 2. The attempt at a solution ^ Is it correct?
