go straight when we tested on the angle board. 2. As the source of light beam was getting farther away from the slit‚ the beam becomes narrower and shorter in addition to fading. This is because light particles escape more when they travel to go through the slit. B. Law of reflection Angle of incidence is the angle formed by a ray incident on a surface and a perpendicular to the surface at the point of incidence. Angle of reflection is the angle between the reflected ray and

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

Refraction and Snell’s Law When an ultrasonic wave passes through an interface between two materials at an oblique angle‚ and the materials have different indices of refraction‚ both reflected and refracted waves are produced. This also occurs with light‚ which is why objects seen across an interface appear to be shifted relative to where they really are. For example‚ if you look straight down at an object at the bottom of a glass of water‚ it looks closer than it really is. A good way

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

refractive index of water is 1.33‚ meaning that light travels 1.33 times as fast in vacuum as it does in water The historically first occurrence of the refractive index was in Snell’s law of refraction‚ n1sinθ1= n2sinθ2‚ where θ1 and θ2 are the angles of incidence of a ray crossing the interface between two media with refractive indicesn1

reflection and dispersion are all processes which happen when a ray of light is shone at either a glass block‚ a mirror or a prism. The ray box is the light source. Mirror When the ray box is shone at a mirror the angle of incidence is always a few degrees different to the angle of reflection. For example‚ if you shine a light ray into a mirror at 60* then it will reflect out at about 57*. Glass Block If I shine a light ray into a glass block then the light would be refracted. It will bend

Third‚ use the light ray box to direct the incident light beam to the air-block boundary at an angle with respect to the normal. Observe the direction of the transmitted beam inside the block and the emerging beam at the block-air boundary. Next‚ use a ruler to draw a line to coincide with the path of the incident light beam. This is the direction
