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 ...

Replica of the original 1951 Weber kettle grill. Weber-Stephen was originally incorporated on May 8, 1893, as Weber Bros. Metal Works. [3]In 1951, the original round charcoal kettle grill was built by George Stephen Sr., a then part-owner of the sheet metal shop in Chicago who sought to improve on the brazier he had been using to cook with at home.

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 .
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 .
Changing orientation of a rigid body is the same as rotating the axes of a reference frame attached to it.. In geometry, the orientation, attitude, bearing, direction, or angular position of an object – such as a line, plane or rigid body – is part of the description of how it is placed in the space it occupies. [1]
The weber is named after Wilhelm Eduard Weber. As with every SI unit named for a person, its symbol starts with an upper case letter (Wb), but when written in full, it follows the rules for capitalisation of a common noun; i.e., weber becomes capitalised at the beginning of a sentence and in titles but is otherwise in lower case.
The Weber number is the dimensionless parameter that determines the onset of this phenomenon called the entrainment limit (Weber number greater than or equal to 1). In this case the Weber number is defined as the ratio of the momentum in the vapor layer divided by the surface tension force restraining the liquid, where the characteristic length ...
