Purpose: To investigate the behavior of light when it passes from air into an optically denser medium. Prediction / Hypothesis: When the light (incident ray) passes from air into an optically denser medium with an angle of incidence equal to zero‚ there would be no refraction. When the light passes at an angle from air into an optically denser medium‚ the light (incident ray) will immediately change direction and bent towards the normal which has an angle of incidence of 0. Method:

Introduction • Snell’s Law is a formula used to describe the relationship between the angles of incidence and refraction‚ when referring to light or other waves passing through boundary between two different isotropic media‚ such as water and glass. • It’s also commonly known as ’’The Law Of Refraction’’ What is light : How is light propagated through different optic medium? • Light is the natural agent that stimulates sight and makes things visible; electromagnetic radiation from about

Project: Practical Investigation Aslam Khan‚ Keenan Wong and Jinhyuk Yeh 2013 Aim: To verify Snell’s Law and find the relationship between angle of incidence and the angle of refraction‚ for monochromatic light passing from air into Perspex. Hypothesis: As the angle of incidence increases so will the angle of refraction (directly proportional). Apparatus: * Laser (Monochromatic light) * Rectangular Perspex * Ruler * Pencil * Paper * Protractor * Calculator

Refraction Refraction refers to the bending of the transmitted light at the interface between two transparent materials. The angle of refraction depends on the angle of incidence and the relative speeds of the light in the two different media and can be found from the relationship [pic] From this equation we see that the direction in which the light is bent depends on whether it is going from a slower to a faster medium or vice versa. Index of refraction The index of refraction of

The Refraction Of Light Through Different Media Mr. Dechene’s SNC2D January 21‚ 2013 Jordyn D. Testable Question: What effects do different mediums have on the angle of light? Hypothesis: If the light goes through different mediums‚ then the light will bend because it is slowing down as it passes through the medium. Equipment: Semicircular plastic dish Polar graph paper Ray box with single slit Water Syrup Experimental Design: A ray box with a single

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

PLANNING: - Title: - An Experiment to investigate the lateral displacement of a ray of light through a rectangular block of a transparent material. Aim: - To investigate the lateral displacement for different angles and how the displacement depends on the angle of incidence when a ray of light enters the Perspex block. Scientific Background: - Refraction occurs when the speed changes when the lights travels from one medium to another medium. If the light travels from a medium to a denser medium
