Calculate the Angle of Incidence and Angle of Reflection

The angle of incidence equals the angle of reflection, at a movement against an obstacle and a reflection or rebound there. The obstacle can be something like a bar or, when referring to light, a mirror. Here, the angles can be calculated for obstacles in a certain angle to the observer.

Angle of Incidence, Angle of Reflection


Surface angle α°
Angle of incidence and reflection β°
Intermediate angle γ°
Direction angle δ°

Please enter two values (not β and γ), the other two will be calculated. The surface angle α must be in the interval ]0°;180°[. Rounding is done to two decimal places. Here you can transfer angle units.

Formulas:
γ = 180° - 2β
α = β + δ
