Reflection and refraction
The law of reflection, why a change of speed bends a wave towards or away from the normal, and wavefronts.
You will be able to
- Use the law of reflection with angles measured from the normal
- Say which way a ray bends when it slows down or speeds up
- Explain refraction with wavefronts (Higher)
