- Q2A student wants to measure the angle of refraction (using the equipment shown) at a boundary from the block into air when the angle of incidence is 20°. Put the following steps into the correct order.Users link answersLinking30s
- Q3Which of the following ray diagrams shows total internal reflection?30s
- Q4Each diagram shows a possible path of light after it enters a semicircular glass block. In which diagram is the angle of incidence as large as possible without total internal reflection occurring?30s
- Q5Total internal reflection can happen …at a boundary where the ray refracts away from the normal (e.g. glass to air).at any boundary between two media.at a boundary where the ray refracts towards the normal (e.g. air to glass).30s
- Q6For light travelling from water to air, the largest angle of incidence possible without total internal reflection is 49°. Match each angle of incidence to the outcome.Users link answersLinking30s
