inconsistency: The light got snuffed out....

Geometric Optics. Heck, I was never good at Geometry. Starting out on concave and convex mirrors. It looked hard to understand at first but it seems a little bit easier now. For the sake of achieving enlightment! I can do this! >Yeah!!<

Here are some important terms to remember:

> center (C) - the center of the spherical mirror

>focal point (F) - the point between the center and the mirror

>vertex - middle part of the mirror

>principal axis - the horizontal line drawn from the vertex of the mirror

Steps for the Ray Diagram of Concave Mirrors:
1. From the tip of the object, draw a line parallel to the principal axis to the mirror. Then, draw another line from the tip of the object to the mirror but this time, the line must pass through the focal point.

2. From the first incident ray, draw a line passing through the focal point (as by the one of the laws of reflection of concave mirrors). From the second incident ray, draw a line parallel to the principal axis.

3. The point where the two rays of reflection intersect is where the tip of the image is. Just draw a perpendicular line connecting the point of intersection and the principal axis and tadah!!! We have an image!

That's an example of an object located beyond C. The following pictures are for other locations of the object:

Note: You can extend the reflected rays until you get an intersection.

Steps for Ray Method of Convex Mirrors:

1. Draw a line parallel to the principal axis from the tip of the object to the mirror. Draw another line (that if extended, would pass through the focal point, which in this case, would be on the other side of the mirror) to the mirror.

2. As by the two laws of reflection of convex mirrors, from the first incident ray, draw a line straight up or perpendicular to the principal axis. From the point of the second incident ray touching the mirror, draw a line parallel to the principal axis.
