A frequency comb is a light source whose spectrum consists of a series of discrete, equally spaced elements.

In infinite dimensions, the spectrum need not consist solely of isolated eigenvalues.

Also, a normal matrix is self-adjoint if and only if its spectrum consists of reals.

It is so-named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the color violet.
