The law of refraction | Physics homework help

 As light travels from one medium to another, the path the light  travels bends in a predictable fashion. This optical phenomena is known  as refraction. The law of refraction can be used to determine the angle  of refraction when the index of refraction is known for both mediums.   The law of refraction is an important physical law with applications in  the field of optics.  The law of refraction is known as Snell’s Law,  named for Willobrord Snell, who discovered the law in 1621.
