We predicted that if we attempted to combine them in the trays it would get messy and the sugar might not be fully dissolved. ... The Method: 1) Sketch four trays onto paper and measure an angle of incidence of 30 and 50 for each. 2) Measure 80mls of water and combine with 20mls of sugar in beaker stir with stirring rod until sugar is dissolved. 3) Pour into tray and place on one of the sketches. 4) Use light box to shine incident rays along your already marked lines of 30 and 50. 5) Record the refracted ray. ... Our results show that although there wasn't much variation,...
