Snell's law is defined as the ratio of the sine of angle of incidence to the sine of the angle of refraction which is constant for a given pair of media and it is also known also as refractive index of the medium.
A tort, in common law jurisdiction, is a civil wrong that causes a claimant to suffer loss or harm, resulting in legal liability for the person who commits a tortious act. It can include the intentional infliction of emotional distress, negligence, financial losses, injuries, invasion of privacy and many other things.
