Discover the precise angle of incidence for light rays or waves easily. Our online calculator uses Snell's Law to help you understand reflection and refraction phenomena. Simply input the refractive indices and the angle of refraction to get instant results, essential for optics and physics studies.
Formula:
The Angle of Incidence (θi) is calculated using Snell's Law, typically from the angle of refraction and refractive indices:
θi = arcsin ( (nr · sin(θr)) / ni )
- θi: Angle of Incidence (in degrees)
- ni: Refractive Index of Incident Medium
- nr: Refractive Index of Refracted Medium
- θr: Angle of Refraction (in degrees)
