What are the two types of mirrors
1.Concave/Converging
2. Convex/Diverging

Real - in front of mirror
Virtual - Behind mirror
How do you find magnification
- Hi/Ho
- Di/Do
What is refraction
When light bends moving from 1 medium to another.
What happens when light goes from low to high density
Bends TOWARDS the NORMAL line
What happens when light goes from high to low density
Bends AWAY from the NORMAL line
What is total internal refraction
When the refracted ray passes the CÏī and all light is refracted
What are the two types of lenses
- Concave/Diverging
2.Convex/Converging
What does transparent mean
