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:

Refraction in Biconcave Lens Now let’s investigate the refraction of light by double concave lens. Suppose that several rays of light approach the lens; and suppose that these rays of light are travelling parallel to the principal axis. Upon reaching the front face of the lens‚ each ray of light will refract towards the normal to the surface. At this boundary‚ the light ray is passing from air into a more dense medium (usually plastic or glass). Since the light ray is passing from a medium in

Light Reflection and Refraction Pre-Lab using PhET I) Introduction: When a light ray strikes a smooth interface separating two transparent materials (like air‚ glass‚ or water)‚ the wave is partly reflected and partly refracted (or transmitted) into the second material. For an example of this‚ imagine you are outside looking at a restaurant window. You can probably see both the inside of the restaurant (from the refracted light) and some of the street behind you (from the reflected light). Similarly

(a) (i) Draw one ray of light on the diagram to show the light shining from the lamp onto the key. Use a ruler. Put an arrow on the ray to show the direction of the light. 2 marks (ii) There is a patch of light on the wall. This light has been reflected from the key. Draw a reflected ray of light on the diagram. Use a ruler. 2 marks (b) There is a dark shadow on the table beside the

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.

REFRACTION THROUGH A LENS Lens: Lens is a transparent refracting medium bounded by two curved surface which are generally spherical. Types of lens: Generally there are two types of lens: 1. Convex lens: It is a lens which is thicker at the middle and thinner at the edges. It is also called converging lens as the light rays converges on passing through it at a point. Focal length of convex lens is taken as positive. 2. Concave lens: it is a lens which is thicker at the edges and thinner at the middle

To What Extent does the Sugar Concentration of Water Affects Its Refractive Index? 1. Introduction 1.1 Background Why do object when placed in a bucket of water bend? This is not magic but it is a property of light known as refraction. The bending of light when it travels from one medium to another is known as refraction. Different mediums have different densities and density is defined as the amount of mass per unit volume. The higher the density‚ the higher is the
