Sentences Containing 'refraction'
The angle of refraction is the angle formed by the refracted ray and the perpendicular to the surface at the point where the light strikes it.
When light passes from air into water or glass, the refracted ray is bent toward the perpendicular, so that the angle of refraction is smaller than the angle of incidence.
When a ray of light passes from water or glass into air, the refracted ray is bent away from the perpendicular so that the angle of refraction is greater than the angle of incidence.
The bending or deviation of light in its passage from one substance to another is called refraction.
Refraction is the source of many illusions; bent rays of light make objects appear where they really are not.
