The conclusion remains the same however r2 is sligh8shorter than r1 according to the image therfore r2-r1 has to be negative not positive undo Tags: Visual edit Mobile edit Mobile web edit

curprev 02:4102:41, 22 April 2022‎ SamyakShirsh talk contribs‎ 23,118 bytes +11‎ The previous editor got the geometry wrong while doing the derivation(specifically they took π/2-θ instead of π/2+θ) and so they wound up with the wrong signs. Please look at the diagram and check if I have corrected it sufficiently undo Tag: Visual edit

curprev 15:5115:51, 25 June 2021‎ 2001:480:91:3304::658 talk‎ 19,514 bytes +1‎ I've seen the phrase "Slit of infinite depth" in multiple articles now. It is a confusing phrase that conjures an image of a rectangular channel or waveguide. Without any context or explanation, it's not appropriate here. I'm changing the wording to "Diffraction by a narrow rectangular slit". undo
