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

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: 1. The semicircular plastic block was placed on the center of the backside of a clean page in

This experiment seeks to demonstrate the law of reflection - the angle of incidence is equal to the angle of reflection when measured from the normal. Equipment Single slit raybox with power supply Paper Ruler Protractor Sharp Pencil Plane mirror Support for mirror (e.g. wooden block with a groove in‚ or plasticine) Method Draw a line on the paper. Place the mirror on the line and support it so it does not move. Shine the beam from the raybox towards the mirror. Use the pencil

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

Question: The effect that the angle of incidence of white light has on the angle of refraction from one transparent medium to another. Introduction: Snell’s law state: When light passes from one transparent medium to another the rays of light refract (bend). Snell’s law (Law of Refraction) states that: n*=sinⅈsinr=n2n1=V1V2 for the purpose of this experiment we will be proving that: sinⅈsinr=n2n1 or n1sinⅈ=n2sinr where n1 and i are the index of refraction and angle with the normal to the surface

focus the light towards the point F f stands for focal point it where all light rays pass forming the centre of the image. The lenses are see through but there is something called a critical where the angle of refraction is greater angle of incidence 90°. In this diagram it describes the Critical angle and the rule and how the Total internal Reflection is created. (google

Refraction of Light in Prisms Questions 1. What is the relationship between the angle of incidence and the angle of refraction? The angle of incidence (formed by the ray of light travelling though air into a slab of rectangular perspex) is not directly proportional to the angle of refraction (angle formed between the ray travelling though perspex and the normal). The graph of the plotted angles of incidence against the angles of refraction is not a straight line and therefore demonstrates this. However
