Presentation on Snell’s Law

Principle objective of this lecture is to present on Snell’s Law. Snell’s law states that a ray of light bends in such a way that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant. Snell’s Law is a law stating that the ratio of the sines of the angles of incidence and refraction of a wave are constant when it passes between two given media.
