Plaster model, after Fresnel, to illustrate the surface of luminous waves - in 3 parts

Surface models were used to illustrate physical phenomena as well as purely mathematical concepts. August Fresnel (1788-1827) proposed his wave theory of light in the 1830s. The surface represents a wavefront of light radiating from a point in a crystal and consists of two shells which touch each other at four points.
