Given a Tube Containing a Lens, Calculate The Focal Length of The Lens and Where The Lens Lies Within The Tube. Plan I plan to set up the apparatus as shown below and change 'b'. To then make the image focus, I will have to change 'c'. When the image is focused, I will measure 'c' and also the magnification of the image. Using this information I will then be able to calculate 'a'. Hypothesis I predict that using the equations stated in the justification, after measuring values for 'c' and 'm'. I will be able to plot them on the graph of 'c' against 'm' Using the equation c = fm + [f - a]. I believe that if all the equations work, a straight line will be obtained. Safety After considering all aspects of this experiment, I have come to the conclusion that there are no significant safety issues. If normal levels of...
