A dark room is a specially darkened studio used for photographic work. As much of the material used in photography is sensitive to light, many operations must be conducted in darkness. Research Dark Room
Diffraction is a term applied to certain phenomena connected with the modification that rays of light undergo in passing close to the edge of an opaque body. Thus when a beam of direct sunlight is admitted into a dark room through a narrow slit, and falls upon a screen placed to receive it, there appears a line of white light bordered by coloured fringes; these fringes are produced by diffraction.
