... 1. Design a circuit to measure the excitation voltage of an LED. Constraints: i) The voltage across the LED must range from zero to a value above the excitation voltage, at least 3V. ii) The current through the LED must be limited by a resistor, that is the LED must never receive the full voltage of ...

... Doppler shift means a frequency shift (and corresponding wavelength shift) of the light. This phenomenon is common to all waves emitted by sources in relative motion with an observer. You probably are familiar with the Doppler shift of sound waves. The frequency and wavelength of the light measured ...

Ion Sound Waves
... Where Mw is the molecular weight, T is the gas temperature and R the gas constant (which is related to K) These look the same but a plasma sound wave is different. First of all since there is a Φ in the plasma, plasma sound has an electric field. Ordinary sound does not. Note that sound in air trave ...

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"".
