Xxx.comTheories of light In the seventeenth century two rival theories of the nature of light were proposed‚ the wave theory and the corpuscular theory. The Dutch astronomer Huygens (1629-1695) proposed a wave theory of light. He believed that light was a longitudinal wave‚ and that this wave was propagated through a material called the ’aether’. Since light can pass through a vacuum and travels very fast Huygens had to propose some rather strange properties for the aether: for example; it must

Osmosis coursework Aim: To investigate the effect of different concentration of a sugar solution on the amount of osmotic activity between the solution and pear pieces of a given size. Define osmosis: Osmosis is a net movement of water/ solution molecules from a region of high concentrated area to a region of lower concentrated area through a semi-permeable membrane which lets smaller molecules such as water through but does not allot bigger molecules like glucose to pass through. The molecules

Practical 5: determination of activation energy of an enzymed catalyzed reaction Introduction: enzymes are complex chemicals that control reactions in living cells. They are biochemical catalysts‚ speeding up reactions that would occur too slowly to be of any usefulness to an organism. Although in organisms‚ it is not necessary for the reactions to be at maximum rate at all times. Enzymes interact with other molecules to produce a stable system in which the products are made when they are
