Some students have an understanding of how a reflective object interacts with light and the eye, but not unreflective objects
The following worksheets may help to identify whether students hold this particular misconception.
Resources to Address This
Seeing with light (5-11)
Ref - SPT HS01 PN02
This resource looks at luminous and non-luminous objects.View Resource
Reflection from any surface (11-14)
Ref - SPT Li03 TL02
Start your teaching with the reflection of light from plane mirrors to establish the law of reflection, then move on to diffuse reflection from irregular surfaces. Emphasise that the law of reflection of individual rays of light applies to both regular and diffuse reflection.View Resource
