Introduction
The shape and location of the image created by
reflection from a mirror of any shape is determined
by just a few simple principles. One of these
principles you already know: light propagates in a
straight line. You will have an opportunity to learn
the remaining principles in this experiment.
To determine the basic principles underlying any
phenomenon, it is best to observe that phenomenon
in its simplest possible form. In this experiment, you
will observe the reflection of a single ray of light
from a plane mirror. The principles you discover
will be applied, in later experiments, to more compli-
cated examples of reflection.
EQUIPMENT NEEDED:
-Optics Bench -Light Source
-Ray Table and Base -Component Holder
-Slit Plate -Slit Mask
-Ray Optics Mirror.
