Introduction:

The purpose of this experiment is to understand the law of reflection using the simplest way to see the phenomenon.

        The problem or the research question being addressed in this experiment is whether or not we will be able to see clearly the reflected ray, and if the law will be correct.

        Reflection is described by the Encarta Encyclopedia as the “phenomenon of wave motion, in which a wave is returned after impinging on a surface.” The laws of reflection state that the angle of incidence is equal to the angle of reflection and that the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane. (see figure 1) When light is reflected on a polished and smooth surface such as a mirror, an image is produced, which appears to be at the same distance as the source of light. (see figure 2)

My hypothesis for this experiment is that we will be able to see the basic laws of reflections being applied when shooting the light to a plane surface mirror and that the angle of incidence will equal the reflected ray.

Experimental Method:

        The way that this experiment will serve its purpose is by using a mirror and the appropriate equipment to observe the law of reflection of light being applied.

        Install carefully the ray table and base and the optic bench on it. Plug in the light source and place ...
