Some Basics 5.1.3 Basic Wave Optics
... A first important conclusion can be arrived at. If we look at an ensemble of waves with the same wavelength, or better: with the same wave vector k = 2π/λ since it contains in addition to the wavelength also the direction of propagation (that's why it's a vector), we note that: An ensemble of suffic ...

... If we know the shape of front at t = 0 then from Huygens principle allows us to determine the shape of wave front at any time t. Let us consider a diverging wave originating from point 0. f1 f2 represent a portion of the spherical wave front at t = 0 Now according to Huygens principle, each point of ...

... Then to measure the intensity of the monochromatic emitted light, we’ll use a photocell *detector*(the photocell in UV designed to measure I° and It and take the ratio but here in spectrofluorometer it will measure the intensity of the monochromatic emitted light). Note the design of the spectrofluo ...

Properties of Waves
... When a sound wave reflects off a hard surface and we hear it again – this is an echo. The distance between a sound and an object can be found by using the wave equation – but remember, it will be double the distance between the sound and the hard surface s = 2d/t Where s is the speed of sound in air ...

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"".
