Refraction
2
How a mirror creates an illusion
3
Refraction Light waves traveling from one medium to another change speed and angle. When traveling from a denser medium (water) to a less dense medium (air) the angle of the light bends away from the ‘normal’
4
Refraction When the light enters into a denser medium from a less dense medium, the opposite occurs, and light is bent towards the ‘normal’ angle.
5
Refraction in a bi-convex lens
Why, then, does the light passing through this lens converge?
6
Light passing through a diverging lens
Why would light passing through a b-concave lens split apart?
