WebX-ray optics is the branch of optics that manipulates X-rays instead of visible light. ... For gold at 1 keV, the critical reflection angle is 2.4°. The use of X-ray mirrors simultaneously requires: the ability to determine the location of the arrival of an X … Mathematically, waves are described in terms of time-varying fields, a "field" being a function of location in space. A propagating wave requires an "effort" field and a "flow" field, the latter being a vector (if we are working in two or three dimensions). The product of effort and flow is related to power (see System equivalence). For example, for sound waves in a non-viscous fluid, we might ta…
