... permeability µrel may depend on the wave’s frequency, so n = κµrel and hence wave speed c/n may change with frequency. This is known as dispersion. For example, at low frequencies, water has a very large dielectric constant κ ≈ 80, which leads to n ≈ 9 and hence rather slow wave speed v = 0.11 c. Bu ...

In addition, radiation offered released electrons enough kinetic energy to transfer to the anode surface and overcome repulsion forces with the negative ...

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"".
