2. REFRACTION OF LIGHT

3. A pencil appears bent or broken when it is partially immersed in water

5. These are two situation that show the effect produced when light travels from one medium to another The effects are due to the change of direction of light when light travels from one medium to another.

9. less dense denser medium i r i = angle of incidence r = angle of refraction i > r Normal line incident ray refraction ray

11. denser medium less dense i r i = angle of incidence r = angle of refraction i < r Normal line incident ray refraction ray
