What is the Incidence?

Incidence refers to the angle at which a light ray strikes a surface, such as a lens or mirror. It is measured from the normal (an imaginary line perpendicular to the surface) to the incoming ray. The angle of incidence is crucial in determining how light will behave upon reflection or refraction according to the laws of optics.

How to Calculate Angle of Incidence?

Angle of Incidence calculator uses Angle of Incidence = Angle of Deviation+Angle of Prism-Angle of Emergence to calculate the Angle of Incidence, Angle of Incidence formula is defined as the angle at which a light wave or other form of electromagnetic radiation strikes a surface, measured from the normal to the surface, and is a critical parameter in understanding the behavior of light at interfaces. Angle of Incidence is denoted by i symbol.
