Law of Reflection 1) At an angle of incidence 41 degrees, the angle of reflection is found to be 41 degrees. This modification to the experiment was suggested by Cristian Bahrim and Wei-Tai Hsu in the American Journal of Physics article: “Precise Measurement of the Refractive Indices for Dielectrics Using an Improved Brewster Angle Method”, Vol. The reflected beam intensity is normalized by the intensity of the laser. This is accomplished by using a beam-splitter and a second light sensor to compensate for the variation of the laser intensity. PASCO Advantage: It is possible to determine the difference in index of refraction for different wavelengths of light. The angle between the reflected ray and the normal is known as the angle of reflection. Angles of Reection & Refraction By convention the angle of incidence is dened as the angle between the incident ray and the surface normalthe direction perpendicular to the surface of the mirror or lens. By convention, the angles for the incident, the reflected, and the refracted light are all measured. This is Brewster’s Angle, which is used to calculate the index of refraction of acrylic. Lab7Reflection and Refraction at a Plane Surface. reflected angle is graphed to determine the angle at which the light intensity is a minimum. The intensity of the reflected polarized light vs. The angle of reflection is measured by a Rotary Motion Sensor mounted on the Spectrophotometer table. The law of reflection states that the angle of reflection. Reflection is defined as the reversal in direction of a particle stream or wave upon encountering a boundary. The reflected light passes through a polarizer and is detected by a Light Sensor. The purpose of this experiment was to test the validity of the Law of Reflection and Snell’s Law (Also known as the Law of Refraction). Light from a diode laser is reflected off the flat side of an acrylic semicircular lens. Below you can see waves of light reflecting off a mirror. Light reflects from a mirror at the same angle as it arrives. When you see the image of your face in a mirror, you are seeing the reflection of light from your face. A plane mirror will reflect parallel rays. In this experiment, light is partially polarized when reflected off a nonconducting surface and Brewster’s Angle is measured. Angles of Reflection When light strikes a mirror it bounces off. The law of reflection (angle of incidence angle of reflection) applies to plane or curved mirrors. ![]()
