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.

The angle between the incident ray and the normal (angle of incidence) is the same as the angle between the reflected ray and the normal (angle of refraction).

Specular and Diffuse 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').
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.
