Concave Mirror - Ray Diagram
Rules of Reflection
*Any incident ray traveling parallel to the principal axis on the way to the mirror will pass through the focal point upon reflection.
*Any incident ray passing through the focal point on the way to the mirror will travel parallel to the principal axis upon reflection.
Procedures 1. Pick a point on the top of the object and draw two incident rays. The first ray should pass through the focal point. While the other ray should be parallel to the principal axis.
2. When the incident rays touched the mirror, these should be reflected according to the rules of reflection (concave mirrors).
3. The point of intersection of the two reflected ray should be marked and known as the top image formed by the object.
4. Repeat procedure 3 but this time, pick a point on the bottom of the object and its reflection intersection should be known as the bottom image formed by the object.

vectors.
>vector quantity is nicely represented by an arrow.
>when the length of the arrow is scaled to represent the quantity's magnitude and the direction of the arrow indicates the direction of the quantity, we refer to the arrow as a vector.
>the sum of 2 or more vectors is called resultant.

light properties...
reflection is the return of light rays from a surface in such a way that the angle at w/c a given rays returned is equal to the angle at w/c it strikes the surface.
refraction is the bonding of an oblique ray of light when it passes from one transparent medium to another.
law of reflection is the angle of incidence equals the angle of reflection.
critical angle is the minimum angle of incidence inside a medium at w/c a light ray is totally reflected.
total internal reflection is the total reflection of light travelling within a medium that strikes the boundary of another medium at an angle or greater than the critical angle.
