Key Stage 2
Meaning
Reflection is when light bounces off a surface.
About Reflection
- Reflection can be specular or diffuse.
 - Specular Reflection happens from a shiny surface and makes an image (you can see a 'reflection').
 - Diffuse Reflection happens from a dull surface and is how we see all objects.
 
| Specular Reflection from the glass makes an image of the sky in the glass. | Diffuse Reflection from the fabric is how light gets from the fabric to our eyes to see it. | 
Key Stage 3
Meaning
Reflection is when a wave bounces off a surface.
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. | 
Specular and Diffuse Reflection
- Reflection can be specular or diffuse.
 - Specular Reflection happens from a shiny surface and makes an image (you can see a 'reflection').
 - Diffuse Reflection happens from a dull surface and is how we see all objects.
 
| Specular Reflection happens from a smooth surface. | Diffuse Reflection happens from a rough surface. |
