Abstract
In this experiment, we used various sources of light and apparatuses to conduct optic
experiments. The optic experiments were used to educate and prove different theories of optic
physics. These theories include laws of reflection, laws of refrac

2.3.6 A Virtual Image
1. I will find S' and y' using the measured values of S, y, and f. Rearranging the mirror formula
and the magnification formula, I can find S' with the equation S' = -1/ (1/s) -(1/f). This gives
me a S' value of -9.6 cm. Now we can f

The projected image seemed inverted and magnified. The mirror has to be viewed a few degrees
away from the horizontal. This makes sense
2.1 Plane Mirrors
1. We measured four values in this experiment; object distance, image distance, object size, and
image size. Object size is equal to 1.11 cm. The object distance is equal to 16.6 cm. The image
distance is equal to 13 cm. The image size i

Abstract
In this lab, the concept of mirrors was explored and demonstrated on. The three
main types of mirrors, plane mirror, concave mirror, convex, are studied. We studied
these mirrors to find out the property of light has on the var
