For example, two identical transparent gratings of 50% duty cycle and the same orientation will appear fully opaque only if the relative phase is π (180 degrees). Gratings with sine wave profiles are used extensively in optics to determine the transfer functions of lenses. A lens will form an image of a sine wave grating that is still ...

A Rinne test should always be accompanied by a Weber test to also detect sensorineural hearing loss and thus confirm the nature of hearing loss. The Rinne test was named after German otologist Heinrich Adolf Rinne (1819–1868); [ 3 ] [ 4 ] the Weber test was named after Ernst Heinrich Weber (1795–1878).
Weber electrodynamics is a theory of electromagnetism that preceded Maxwell electrodynamics and was replaced by it by the end of the 19th century. [1] Weber electrodynamics is mainly based on the contributions of André-Marie Ampère , Carl Friedrich Gauss and Wilhelm Eduard Weber .
Minnesota Vikings quarterback J.J. McCarthy has had a second surgery on his injured right knee. Vikings head coach Kevin O'Connell confirmed the procedure while speaking with reporters on Wednesday.
A Weber bar is a device designed to detect gravitational waves, first devised and constructed by physicist Joseph Weber at the University of Maryland. The device consisted of aluminium cylinders, 2 meters in length and 1 meter in diameter , antennae for detecting gravitational waves .
The Weber number appears in the incompressible Navier-Stokes equations through a free surface boundary condition. [ 3 ] For a fluid of constant density ρ {\displaystyle \rho } and dynamic viscosity μ {\displaystyle \mu } , at the free surface interface there is a balance between the normal stress and the curvature force associated with the ...
