... Be able to calculate the frequency of a sine wave given the time for one period. Given two sine waves of the same frequency but different phase, be able to assign one as the zero phase reference, and then calculate the phase difference between the two sine waves. For a three phase supply, with each ...

... A way of describing how diffraction occurs was invented by Christian Huygens (1629-1695) in about 1679 and was modified much later into the form we now use by Augustin Fresnel (1788 1827). Huygens' construction is a method for locating the new position of a wave front. Starting from a known wavefron ...

High-resolution measurement of phase singularities
... difference between two subsequent diffraction orders is exactly equal to one wavelength. This means that the screw-like phase distribution produced by the CGH has an additional 2p phase shift. This will lead to a beam in the second order which carries a singularity that has twice the strength of the s ...

... b. The spring constant, k, is given by the extension, ∆x, for a given applied force F: F = -k∆x or k = F /∆x. For the same force the longer spring has a greater extension, therefore it has a smaller spring constant. c. A spring is an object that can be compressed or stretched away from equilibrium l ...
