... Snell’s law contd. The path of the refracted ray is always reversible. The ray follows the same path when going from b to a as when going from a to b. The path of the reflected ray is also always reversible. The intensities of the reflected and refracted rays depend on the angle of incidence, the i ...

Thomas Young (scientist)

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"".
