A -23% error between the two angles was calculated. In the second run, the angle of incident was 0.1 degree less than the angle of reflection. A 52% error between the two angles was calculated. In the third run, the angle of incident was 1 degree less than the angle of reflection. A 1.3% error was calculated between the two angles. In the fourth run, the angle of incident was 0.5 degree bigger than the angle of reflection. A -70% error was calculated

Unformatted text preview: between the two angles. The angle in run three is the most accurate because it has the least percent error. The law of reflection states that the angle of incidence is equal to the angle of reflection. My lab does not verify the law of reflection because the angle of reflection and the angle of incidence do not equal each other. The angles appeared to be equal, but the measurements told otherwise. The angles were marked with a pencil and drawn with a ruler. Afterwards, the angles were measured with a protractor. An error could have occurred during these processes....
