- Light
- reflection
- a rough surface
- the light will bounce of in random areas depending on the shape
- rock
- limestone
- sandpaper
- smooth surface
- the light will bounce at the same angle as it comes on to the surface
- Mirror
- the angle of incidence is equl to the angle of refelction
- a rough surface
- refraction
- refraction occurs when light hits something transparent
- When refraction occurs it changes speed and direction of the light
- the line at which the light is coming at the glass block is called the incidence ray
- the ray which then comes out of the glass block is called the refracted ray
- as soon as light leaves the glass block it goes back to the angle at which it was travelling
- colour
- spectrum
- contains 7 colours
- red orange yellow green blue indigo violet
- contains 7 colours
- we are able to see colours because all objects dont reflect every colour
