The angle between the ray which is refracted at a surface and the normal to that surface.
(Generally identified as a "numbered" theta, such as 2, but sometimes as .) The angle at which light travels after passing through an interface between two media, measured between the path of the light and the normal to the interface. See this page of this module to learn more about refraction.
The angle formed between the normal and a refracted beam.
The angle between the refracted ray and the normal drawn to the point of refraction.
the angle between a refracted ray and a line perpendicular to the surface between the two media at the point of refraction
The angle between the normal and the refracted ray (reflected)
The angle of the refracted ray which is measure between the ray and normal.
The angle between a deviated ray of light that has passed through the boundary between two transparent media and the vertical to the boundary surface at the point of emergence in the second medium.
The angle between the line perpendicular to the surface the waves are striking (normal) and the direction of the waves after they (incidence ray) have crossed the barrier.
the angle at which a refracted ray of energy leaves the interface at which the refraction occurred. It is measured between the direction of the refracted ray and a perpendicular to the interface at the point of refraction.
The angle formed between a refracted ray and the normal to the surface. This angle lies in a common plane with the angle of incidence.
Angle between direction of motion of waves and a line perpendicular to surface the waves have been refracted from.
The angle between the direction of propagation of an electromagnetic or acoustic wave (or ray) refracted by an optically homogeneous body and the local normal to that body.
