    Key Questions:

    1. (Physics Only) Explain how the differences in velocity, absorption and reflection between different types of wave in solids and liquids can be used both for detection and exploration of structures which are hidden from direct observation?
    2. How should ray diagrams to illustrate the refraction, be constructed?
      • Use a ruler;Wave fronts at right angle to ray; Wave fronts closer together when the wave travels slower.
    3. (HT only) What is the cause of refraction?
      • (HT only) Due to the difference in velocity of the waves in different substances, caused by the density of the Particles.
    4. (HT only) How can refraction be explained?
      • (HT only) Wave front diagrams can be used to explain refraction in terms of the change of speed that happens when a wave travels from one medium to a different medium.
