Diffracting Sentence Examples
In experiment under ordinary circumstances it makes no difference whether the collecting lens is in front of or behind the diffracting aperture.
By the principle of energy the illumination over the entire focal plane must be equal to that over the diffracting area; and thus, in accordance with the suppositions by which (3) was obtained, its value when integrated from E= co to = -1-x, and from n = - oo to n = -1-oo should be equal to ab.
