Reflection of light (5-11)
Ref- SPT HS01 PN06
Light beams are reflected from surfaces according to the law of reflection, which states that 'the angle of incidence is equal to the angle of reflection'. Build up the diagram in stages.View Resource
The virtual image in a plane mirror (11-16)
Ref - Practical Physics; Light and optics; Reflection of light;
Identifying that the image in a plane mirror is virtual. Trace the rays from the source to the mirror and the reflection. Locate the virtual image (where the light seems to come from). The light does not stay 'on the mirror'.View Resource
