Snell Calculator

Snell’s law, also known as the law of refraction, describes the direct relationship between the angle of incidence and the angle of refraction when dealing with light or other beams that pass through a certain media. It is a principle and a formula used by physicists in optics, in ray tracing to determine the angles of incidence or refraction or to find out the refractive index of a material.

While the calculus can be easily done manually, Snell Calculator ca help you out and carry out the task for you. It is a simple and install-free application ready to apply Snell’s law and principle to perform the calculations without you having to touch the pen and paper.

There are three different parameters that you need to provide to Snell Calculator. It requires you to fill in values for the refractive index incident medium and the refractive index target medium. In other words, it uses the refractive indices of the incident and the target optical media, as well as the angle of incidence to output the angle of refraction and the critical angle at which the light bends when going through the chosen media.

While calculating the values should not be so difficult having the formula in front of you, it is probably much easier and faster to use a specialized dedicated calculator to apply Snell’s law.
