| angle of incidence |
The angle between the direction of propagation of an electromagnetic or acoustic wave (or ray) incident on a body and the local normal to that body (although this normal may not be well defined, as that for a cloud, eg). May also describe beams of particles in the broadest sense. Compare angle of arrival.

| angle of reflection |
The angle between the direction of propagation of an electromagnetic or acoustic wave (or ray) reflected by a body and the local normal to that body (although this normal may not be well defined, as that for a cloud, eg). May also describe beams of particles in the broadest sense. See reflection.
