Below there are three objects a mirror‚ a glass block and a prism‚ it shows and tells you underneath each of the objects picture a description of what happens when light ray is shone on it. The source of light is a light bulb from a ray box. If a beam of light of one colour is shone through a prism‚ the direction of the beam is changed by the prism. This is because the two faces of the prism through which the light passes are not parallel. If white light is used the prism splits up the light into

Light Effects Refraction‚ 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

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 the lab book. Then‚ its outline was traced and the location of the center of the center of the flat side was marked. 2. A single ray of light from the ray box was directed to the center of the flat side at an angle of incidence of about 0. The location

The green line represents the original beam of light that is incoming from the laser. When light passes through the water tub‚ it undergoes both reflection from the surface and refraction. The yellow arrowed line shows the beam of light that is reflected and the red arrowed line shows the pathway of the light beam after it has undergone refraction. It can be noticed that there is a lateral displacement

Investigating Snells Law Investigating Snell’s Law Research 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
