Key Stage 2
Meaning
A mirror reflects light so we can see a perfect image.
Reflection from shiny surfaces is when light bounces off a material creating an image that we can see.
About Reflection form Shiny Surfaces
- When a surface is shiny we can see a reflection on the surface.
- A mirror is a shiny piece of metal that reflects all of the light that hits it and allows us to see an image.
- Mirrors are said to be reflective.
- If a surface is dull you cannot see an image and it is not called reflective, but it still reflects the light.
 |
 |
| You can see the reflection of the mountain and clouds on the surface of the water. | The glass reflects the image of the clouds. |
 |
 |
| These glasses are very reflective. | You can sometimes see a reflection is a person's eye. |
Key Stage 3
Meaning
Specular Reflection is when light bounces off a flat surface to produce a an image.
About Reflection
- All waves can be reflected.
- The reflection of sound is called an echo.
The Law of Reflection
- The Law of reflection states that the angle of incidence is equal to the angle of reflection.
 |
| Specular Reflection from the glass makes an image of the sky in the glass. |
About Specular Reflection
- Reflection of light can be specular or diffuse.
- Specular Reflection happens from a shiny surface and makes an image (you can see a 'reflection').
 |
 |
| Specular Reflection happens from a smooth surface. | Diffuse Reflection happens from a rough surface. |
