... Sound is also a wave, but in this case, instead of the electromagnetic field, it is the air pressure that oscillates at a much slower rate. In the case of light, it is the electric field oscillating at a very high frequency. The electric field is also responsible for hair clinging to a synthetic jumper ...

DeBroglie Hypothesis
... Even neutrons have shown interference phenomena when they are diffracted from a crystal structure according to the DeBroglie Hypothesis: = h/p . Note that h is very small, so that normally will also be very small (unless the mv is also very small). A small means very little diffraction effects ...

In this analysis, the addition of an quarter-wave plate at the back-focal plane of the objective will leave the 0th order undiffracted light unchanged but the effect of the quarter-wave plate on the diffracted light will be to change the cos in the second term to sin, thus converting a phase-modulat ...

Thomas Young (scientist)
.jpg?width=300)
Thomas Young (13 June 1773 – 10 May 1829) was an English polymath and physician. Young made notable scientific contributions to the fields of vision, light, solid mechanics, energy, physiology, language, musical harmony, and Egyptology. He ""made a number of original and insightful innovations""in the decipherment of Egyptian hieroglyphs (specifically the Rosetta Stone) before Jean-François Champollion eventually expanded on his work. He was mentioned by, among others, William Herschel, Hermann von Helmholtz, James Clerk Maxwell, and Albert Einstein. Young has been described as ""The Last Man Who Knew Everything"".
