EXPERIMENT 8 PFUND REFRACTION A narrow beam of light passes through the face of a glass plate, then undergoes a diffuse reflection from the rear surface of the plate. The diffused light travels back toward the face. Part of this light passes through the face and part undergoes total internal reflection and reflects back to illuminate the rear surface. When viewed from the front, the result is

Experiment 2: total internal reflection If light is incident on a glass–air interface at an angle greater than the critical angle, then it undergoes total internal reflection. The aim in this experiment is to observe rays that undergo vary-ing numbers of total internal reflections, depend-ing on the angle of incidence of the laser beam. The results can be used to determine the refractive

Experiment 9.4 verified that total internal reflection will occur if light passes from a medium of greater refractive index into one of a lesser refractive index if the angle of incidence is greater than the critical angle (𝜃𝑖 > 𝜃𝑐 ). This means that there is zero refracted light, and all light is reflected back into the medium. If the incidence angle is less than the critical
The object of this experiment is to study the laws of reflection and refraction. Theory: The Law of Reflection states that the angle of incident ray equals the angle of the reflected ray, or θi = θR The Law of Refraction (Snell’s Law) relates how a ray of light will behave when passing from one media to the other. It is given by: n1sinθi = n2 sinθ r where n1 and n2 are the indices of
In this experiment you will look at two phenomena related to refraction: Dispersion and Total Internal Reflection. Dispersion introduces a complication to the Law of Refraction, which is that most materials have different indexes of refraction for different colors of light.
