|---|---|
| transverse wave consisting of oscillating electric and magnetic fields at right angles to each other; form of energy that travels as a wave through space | electromagnetic wave |
| the turning back of an electromagnetic wave at the surface of a substance | reflection |
| the angle between a ray that strikes a surface and the normal to that surface at the point of contact | angle of incidence |
| the angle formed by the line normal to a surface and the direction in which a reflected ray moves | angle of reflection |
| an image formed by light rays that only appear to intersect | virtual image |
| an inwardly curved, mirrored surface that is a portion of a sphere and that converges incoming light rays | concave spherical mirror |
| an image formed when rays of light actually intersect at a single point | real image |
| an outwardly curved, mirrored surface that is a portion of a sphere and that diverges incoming light rays | convex spherical mirror |
| the alignment of electromagnetic waves in such a way that the vibrations of the electric fields in each of the waves are parallel to each other | linear polarization |
