Lab 26 Reflection And Refraction Of Light

This laboratory was designed to investigate the behaviour of light as it travels through a denser into a less dense medium.

Lab 26 reflection and refraction of light. To be able to understand the behavior of light when it reflects from an optical surface reflection and when it passes from one optical medium to another refraction.

Refraction of light part ii introduction.

Ray box with comb. The object of this experiment is to study the laws of reflection and refraction. We will use snell s law for refraction to measure the refractive index of a glass plate and to analyze the phenomena of total internal reflection. The reflection and refraction of light.

In figure 26 3 b the light travels from a material water with higher index of refraction to a material of a lower index of refraction air. Light rays change direction when they reflect off a surface move from one transparent medium into another or travel through a medium whose composition is continuously changing. This angle is called the critical angle. The figure above implies that the incident ray can be increased to some angle where the refracted light is perpendicular to the normal.

The law of reflection states that on reflection from a smooth surface the angle of the reflected ray is equal to the angle of the incident ray. Experiment 26 reflection and refraction advanced reading. In this lab we will verify the law of reflection and locate the virtual image formed by a flat mirror. The law of reflection.
