Investigation: What effects displacement of a ray of light? Variables * The angle the light hits the block at * The width of the block * The colour of the light * Light intensity Predictions * The larger the angle the larger the displacement. (See Diagram) In the diagram I have used snell's law to find the refracted angle, Snell's law is that for glass Sin i Sin r = 1.5 By using this I have been able to work out accurate results without doing an experiment. * The displacement will be directly proportional to the width of the block. I.e. The wider the block the larger the displacement E.g. if you double the thickness of the block then the displacement will double (See Diagram) Plan 1 The apparatus that I need for the experiment is 1 Protractor 2 Ray Box 3 Ruler 4 Blank page 5 Glass block 6 Power Pack The measurements to be taken are: the size of the blocks : The size of the displacement 5 readings will...
