PHYIC CALCULATOR
Snell’s Law Calculator
A precise tool.
What is the Snell’s Law Calculator & How does it work?
Snell’s Law describes the relationship between the angles of incidence and refraction when light passes through the boundary between two different media.
The law is expressed as:
n_1 sin(theta_1) = n_2 sin(theta_2)
n = refractive index, ΞΈ = angle of incidence or refraction
This calculator allows you to determine either the angle of refraction or the refractive index given the other parameters.

Frequently Asked Questions
What is Snell’s Law?
Snell’s Law describes how light bends when it moves from one medium to another, relating the angles of incidence and refraction to their respective refractive indices.
How do I use this calculator to find the angle of refraction?
Input the refractive index of the first medium (n1), the angle of incidence (ΞΈ1), and the refractive index of the second medium (n2). The calculator will then compute the angle of refraction (ΞΈ2).
Can this calculator help me find the refractive index?
Yes, if you know the angles of incidence (ΞΈ1) and refraction (ΞΈ2), along with one of the refractive indices (n1 or n2), you can solve for the unknown refractive index.
What are some common applications of Snell’s Law?
Snell’s Law is used in various fields such as optics, lens design, and fiber optics to understand how light behaves when passing through different materials.
Is this calculator accurate for all types of media?
This calculator uses Snell’s Law, which assumes ideal conditions. For more complex media or situations, additional factors may need to be considered.
