Outcomes
- Pupils can state and use the Law of Reflection.
- Pupils can explain refraction as due to a change of speed in different media.
- Pupils can predict the change in direction of a wave due to refraction, including examples using light (including dispersion) and in water, using wave front to explain what is occurring.
Specification References
Starter
- Ask pupils how a mirror works. Link reflection to smoothness of a surface.
- (If you're feeling really brave you could ask why mirrors reflect things right-to-left but not top-to-button.)
Main Body of Lesson
- Use small bulb, radiant heater, two parabolic mirrors, camera and temperature probe to demonstrate that heat waves are reflected just as light waves are.
