In mathematics, Fresnel's '''wave surface''', found by [[Augustin-Jean Fresnel]] in 1821, is a [[quartic surface]] describing the [[propagation of light]] in an [[optically biaxial crystal]]. Wave surfaces are special cases of [[tetrahedroid]]s which are in turn special cases of  [[Kummer surface]]s.

In projective coordinates (''w'':''x'':''y'':''z'') the wave surface is given by
:<math>
\frac{a^2x^2}{x^2+y^2+z^2-a^2w^2} + \frac{b^2y^2}{x^2+y^2+z^2-b^2w^2} + \frac{c^2z^2}{x^2+y^2+z^2-c^2w^2} =0
</math>
