... 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 ...

... The equation for simple harmonic motion is given by x = Asin(t). The speed is given by v = A cos(t). At the lowest point the speed is a maximum (t = 0), hence v = A = 2.8 s-1 0.15 m = 0.42 m.s-1. b. The acceleration is a = dv/dt = -2A sin(t). At the end of its path the acceleration is a maxi ...

... 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 ...
