According to Snell’s law, the angle of refraction, θr, depends on the angle of incidence, θi, and the ratio of the refractive indices of the two media that make up the interface. If the media have identical refractive indices, there is no refraction and the angle θr=θi. Similarly...

Noun1.angle of refraction- the angle between a refracted ray and a line perpendicular to the surface between the two media at the point of refraction angle- the space between two lines or planes that intersect; the inclination of one line to another; measured in degrees or radians ...
A ray of yellow light crosses the boundary between glass and air, going from the glass into the air. If the angle of incidence is 20 degrees, what is the angle of refraction? In an experiment to determine the refractive index of water, a student measures the angle of incidence to be 45...
