The speed of light in vacuum is a universal constant, meaning that it is the same in any gravitational field. This universality of the speed of light can be explained by the fact that the speed of light is always measured by a freely-falling observer, and the local laws of special relativity are invariant with respect to a Lorentz transformation (i.e. a boost), so they are also invariant under a gravitational field. Under a gravitational field, the speed of light also appears to be affected by the mass of the source. This is because the gravitational field of a massive object is itself proportional to the mass of the object. Therefore, the speed of light as measured by a freely-falling observer is multiplied by 1−v/c for a particle in a gravitational field (where v is the velocity of the particle with respect to the freely-falling observer). The phenomenon of the speed of light varying with the mass of the source is referred to as gravitational time dilation.

The second major area in which mathematics is used is in theoretical and mathematical optics, the study of optical phenomena such as reflection, refraction, diffraction, and scattering. Optics deals with light which propagates in free space or in certain optical media, and which has properties different from that of light traveling in a vacuum. Optics is studied in more detail in the sub-article on physics of light. In this sub-article, as well as in the sub-article on mathematics of the theory of optical media, we provide a variety of mathematical models describing the optical properties of various optical media. The models are all based on the optical-theoretical formulation of the electromagnetic field equations.

Briefly, these equations state that the electric and magnetic fields are related to the Maxwell stress tensor, which is a function of the dielectric permittivity and magnetic permeability of the medium. The optical-theoretical formulation of Maxwell's equations was derived by James Clerk Maxwell in the 1870s. The use of these equations for the study of optical phenomena was initiated in the 1930s by Michael J. Rowland and Harold I. Smith. In this approach, the electric and magnetic fields can be separated into amplitudes and phases, and Maxwell's equations are then reduced to two equations for each field. The remaining two Maxwell equations then determine the phase and amplitude relations of the optical fields. Some of the most important optical phenomena such as reflection, diffraction, and interference can thus be described by an equation of the form
