WebIf i is the angle of incidence of a ray in vacuum (angle between the incoming ray and the perpendicular to the surface of a medium, called the normal) and r is the angle of refraction (angle between the ray in the medium and the normal), the refractive index n is defined as the ratio of the sine of the angle of incidence to the sine of the angle … WebThe Angle of Deviation. The amount of overall refraction caused by the passage of a light ray through a prism is often expressed in terms of the angle of deviation ().The angle of deviation is the angle made between the …
