Lab 09 Reflection And Refraction Of Light

Ray box with comb.

Lab 09 reflection and refraction of light. If a light ray bends towards the normal line this bending towards the normal means that the speed of light has decreased. The angle of refraction is the angle between the normal and the refracted ray in order to figure out whether light is speeding up or slowing down you need to compare the direction the light ray bends. This laboratory was designed to investigate the behaviour of light as it travels through a denser into a less dense medium. The angle of reflection and the angles do not depend on the nature of the material.

To study the reflection of light by a flat surface and to study the refraction of light through straight and curved surfaces. Plane reflection set up the optics bench so that you have a single ray of light striking the plane mirror details provided in lab. Mirrors are an excellent reflector since hardly any light is absorbed. 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.

Light bounces off the mirror at the same angle that it came in law of reflection. Refraction of light part ii introduction. Gamoi paisley lab partner. Lab 10 reflection and refraction introduction geometric optics is one of the oldest branches of physics dealing with the laws of refraction and reflection.

Reflection and refraction of light submitted by. Spring 2009 home lab week 5 refraction of light. The objective of this experiment is to study and verify experimentally the laws of reflection and refraction of light. Lab preparation when light travelling through air encounters a different material part of the light energy is reflected back into the air and part of it is transmitted into the glass experiencing an abrupt change.

Experiment with 1 then 2 and even 3 mirrors a laser pointer to reflect the light around the room. The law of reflection was known to the ancient greeks who made measurements that supported this law. Pratik kc albina mavlyutova mateo flores mohammed shakil objective. In refraction we will learn that the angle of the ray when transmitted through the material changes and depends on the speed of light in the two materials.

To examine the phenomena. Quantify the observed refraction as light passes from one medium to another measure the critical angle for total internal reflection and compare it to the predicted value for the medium activity 1. Light light reflection and refraction. Try many different angles.

Reflection and refraction course. Then answer the following questions.
