* '''Developmental Questions (What discussion questions)'''
#What is a wave? (carries energy)
#Have you seen any waves?
#Can two waves meet? (Water, ropes etc)
#When they encounter an obstruction what do they do? (They bounce back, they bend around, etc_
#What happens when they meet? The energy increases or decreased
#In this image, what do you see happening to the wavefronts - they get reflected, they get refracted
#How can we represent this using a ray diagram?
#This can be constructive or destructive interference
