3short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is the law of reflection?Show answer
The law of reflection states that the angle of incidence equals the angle of reflection. The incident ray, the reflected ray and the normal all lie in the same plane.
What is the image in a plane mirror?Show answer
A flat (plane) mirror forms an image that is:
What is refraction?Show answer
Refraction is the change of direction of light when it passes from one material into another. It happens because light travels at different speeds in different materials.
