Project Report from the year 2011 in the subject Physics - Optics, grade: 1.0, Lancing College, language: English, abstract: This practical report outlines procedures for measuring the power of convex lenses and improvements to standard methods. I have been given a box of 54 lenses with different powers, marked with different colours. My aim was to verify these given values, to find an improvement of my measurements and then to use this method to find the power of the lenses with unknown powers in the box and assemble them to the colour groups. The power has been calculated from measured values of u (distance from object to lens) and v (distance from focussed image to lens) by using the lens equation.
