Reflection and Refraction of Light Essay

ObjectiveThe aim of this experiment is to prove the laws of reflection and refraction, and to determine the fish of the total inbred reflection and the index of refraction in the experiment.TheoryThe theory organism experimented in this procedure is that of Willebrord Snell. From his theory we gain that the incident give off, the normal stock certificate and the refracted rhenium all lie on the same plane. We also understand that the relationship is defined in a ratio with the following equationWhich means that the ratio of the sine of the angle of relative incidence to the sine of the angle of refraction, I equal to the ratio of the speed of accrue in the first medium and the speed of light in the refracting medium.ProcedureWe set up the optics track, light source and the ray control panel. We then aligned the flat fount of the mirror with the ray of light from the light source. We rotated the ray table in increments of 10 . The first set were done going clockwise. at one time done we then did the same thing simply going counterclockwise. This gave us the Angles of Reflection. FromThe two Angles of Reflection we were able to calculate the modal(a) Angles of Reflection, listed in shelve 1. For the Law of Refraction, we replaced the mirror with a Acrylic cylindrical lens. We rotated the ray table clockwise by increments of 10 again. We repeated the same measurements but instead with counterclockwise angles. From the two angles of refraction we were able to calculate the average angles of refraction. Finally, we aligned the flat side of the lens so that incoming light ray struck the cylindrical surface. We rotated the ray table until the refracted ray disappeared completely and only the reflected ray was visible. This is the angle of incidence. This gave us our angle of incidence theoretical value. From this we were also able to calculate the angle of refraction.
