Snell's Law, also known as the law of refraction, is a fundamental principle in optics that describes the relationship between the angles of incidence and refraction when a light ray passes through two different mediums.
Snell's Law is only applicable to light rays passing through two mediums with a smooth, flat interface. It also assumes that the light rays are traveling in a straight line and that the speed of light is constant in both mediums.
Scientists use advanced experimental techniques and mathematical models to study the behavior of light at different angles of incidence and in various mediums. They also study the effects of introducing irregularities or varying the speed of light in different mediums.
Snell's Law is used in various fields such as optics, medicine, and engineering. It is the basis for the design of lenses, prisms, and other optical devices. It is also used in the production of prescription eyeglasses and in medical procedures such as laser eye surgery.
Snell's Law is a simplified model that does not take into account factors such as diffraction, dispersion, and polarization of light. In scenarios where these factors play a significant role, Snell's Law may not accurately predict the behavior of light.
