{{#category_index:E|eikonal equation}} (ī kōn’ ∂l) (from Greek $\iota \kappa o\nu$ (ikon) meaning image. An equation derived from the wave equation through the substitution of a harmonic wave trial solution into the wave equation. In one form of the eikonal equation seen in physics literature, the local velocity $V$ is compared to a reference velocity $V_{R}$(analogous to comparing a velocity to the speed of light in vacuum):
