refraction of light

Knowledge you need to have:

• Knowledge that refraction occurs when waves pass from one medium to another. 

• Description of refraction in terms of change of wave speed, change in wavelength and change of direction (where the angle of incidence is greater than 0°), for waves passing into both a more dense and a less dense medium. 

Skills you need to develop:

• Identification of the normal, angle of incidence and angle of refraction in ray diagrams showing refraction.
