# The term "angle of deviation" is used in reference to what ?

 +1 vote! +7 you voted Answer by  Qwedsa (96) In optics, the angle of deviation is used to refer to the angle that a light beam makes after it has had it's path altered with the original path that is was taking when it has its course changed by the process of refraction. At the critical angle the light beam is reflected.

 +1 vote! +6 you voted Answer by  suzieQ (21) When light passes through a different medium, it refracts. The difference in the angle between the incoming light ray and the outgoing light ray is the angle of deviation. The angle of deviation may be different for different wavelengths of light because the index of refraction is slightly different.
