Shai Manor Physics HL 22/10/2004 Planning Lab: Planning A: Aim: Investigating the refractive index of different types of transparent solids and to learn how density affects the refractive index. Hypothesis: Density will affect the refractive index in terms of making it "bigger or smaller". By this I mean it will make the angle at which it refracts bigger or smaller in relation to the glass used. This is because the denser the glass, the closer together the particles are packed. The closer they are packed, the more particles the light has to go through. Therefore, the higher the density, the slower the light goes through the glass. The slowing down of the light is the amount it refracts. I am thus expecting the speed of light to be slower through the glass. Variables: Independent: type of glass used Dependant: refractive index Controlled: Weighing scale, beaker, amount of water poured into beaker, lamp Planning B: Material: - 1 Weighing scale - 1L beaker -...
