... An intensive light beam is introduced into the axis of an out flowing water jet. Because of repeated total reflections the light can not leave the jet and it is forced to follow the water jet. It is expected that the jet remains completely darken unless the surface contains small disturbances. This ...

Part 2 . Physical Optics
... where the approximation R1 R2 < R 2 has been made. There are two terms to this phase difference. The second is a quadratic phase term identical in form to the result obtained from spherical and plane waves. The pattern will be symmetric around the line connecting the two sources, and its appearance ...

Polarized Light
... • If a linear polarizer is rotated and the transmission goes to zero at some angle, then input is linearly polarized, DONE. • If no there is no variation with polarizer rotation, light is circularly polarized, unpolarized, or a mixture of these – to distinguish between these, put in λ/4 plate before ...

X-Ray and Neutron Reflectivity - Physik der molekularen und
... Generally, the order of magnitude for δ and β is similar to the X-ray case. However, since the scattering length b of the nuclei varies non-monotonously across the periodic table, as opposed to the case of X-rays, the contrast between two given elements is different for Xrays and for neutrons. Thus, ...

L6 POLARISATION
... In some materials light with different polarisations travels at different speeds. Since we can regard any wave as the superposition of two plane polarised waves, this is equivalent to saying that one beam of light travels at different speeds in the material, that is the material has different refrac ...

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"".
