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

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
