P7.3+-+Reflection+and+Refraction

Topic: P7.3 - Reflection and Refraction

Objectives (you will know):
 * the patterns of reflection and refraction of plane waves in ripple tank
 * what causes refraction
 * how wave behaviour can be used to explain reflection and refraction

Tacoma Bridge Video

Teacher talk:
 * Representing waves:
 * Displacement vs distance (last lesson)
 * Wavefronts




 * Reflection is:
 * what happens when a wave reaches something it can't travel trough
 * Ripple tank videos (number 2)


 * Refraction is:
 * what happens at a boundary between two different mediums that the wave can travel through
