#What is a wave? (carries energy)
#Can two waves meet? (Water, ropes etc)
#What happens when they meet? The energy increases or decreased
#The interaction between two waves is called interference
#This can be constructive or destructive interference

The objective is to demonstrate how we can explain the phenomena of light - reflection, refraction - through the wave model.
The teacher must reconcile the rays to the wave model.
