How else do you look pretty in the morning?

2. Reflection
The turning back of an electromagnetic wave at the surface of a substance

3. Reflection The texture of a surface affects how it reflects light
Diffuse reflection- light that is reflected from a rough, textured surface
Specular reflection- light reflected from smooth, shiny surfaces

7. ANGLES
Angle of Incidence- the angle between a ray that strikes a surface and the normal to that surface at the point of contact θ
Angle of Reflection- the angle formed by the line normal to a surface and the direction in which a reflected ray moves θ′
θ = θ ′

9. Flat (Plane) Mirrors Simplest of all mirrors
Light rays bounce off objects in front of the mirror and reflect from the mirror’s surface.
An object's reflection is said to be located behind the mirror (not literally)
The object distance (do) is equal to the image distance (di)

10. VIRTUAL IMAGES
The only thing flat mirrors form (albeit self-consciousness)
Virtual image- an image formed by light ray that only appear to intersect
Can never be displayed on a physical surface

11. RAY DIAGRAMS
Ray diagrams- drawings that use simple geometry to locate an image formed by a mirror
