Refraction

Learning Intention

We are learning that light behaves as a wave and can slow down and change direction when it hits different surfaces

Success Criteria

I will describe how a Convex Lens causes light to converge and how a Concave lens causes light to diverge

Light box practical activities, suggested worksheets to accompany these observations

Refraction theory videos and notes

Why does light appear to bend when it hits glass?

Why does light appear to slow down or speed up?

Extension: Snell's Law is the mathematical equation that explains the behaviour of light as it travels through different medium
