Formula 3 - Angles and Wavelengths

In this template, you will be able to use the third relationship of Snell's Law to determine the parameters stated below. 
Formula:﻿
sin(θ1)sin(θ2) = λ1λ2\cfrac{sin(\theta_{1})}{sin(\theta_{2})}\ =\ \cfrac{\lambda_{1}}{\lambda_{2}}sin(θ2​)sin(θ1​)​ = λ2​λ1​​
CalculatorsAngle of Refraction (given the wavelengths)
Angle of Incidence (given the wavelengths)
Wavelength of wave in Medium 1 (given the angles)
Wavelength of wave in Medium 2 (given the angles)
Critical Angle (using the wavelengths)
Refractive Indices of the mediums and velocities of the waves in each medium (given the wavelengths)
