# Prism Refraction Angle Calculator

The Prism Refraction Angle Calculator is a useful tool for optical studies and applications involving prisms. It calculates the angle of refraction of light passing through a prism, based on the known angles of incidence, emergence, and deviation. Understanding this angle is crucial in fields like optics and photonics, where precise control of light paths is required.

**Formula**

The formula for calculating the Prism Refraction Angle (PRA) is: PRA = AOI + AOE – AOD. In this formula, PRA represents the prism refraction angle, AOI is the angle of incidence, AOE is the angle of emergence, and AOD is the angle of deviation.

**How to Use**

- Enter the Angle of Incidence (AOI) into the corresponding field.
- Input the Angle of Emergence (AOE).
- Provide the Angle of Deviation (AOD).
- Click the “Calculate” button to compute the Prism Refraction Angle.

**Example**

If the Angle of Incidence (AOI) is 30 degrees, the Angle of Emergence (AOE) is 40 degrees, and the Angle of Deviation (AOD) is 20 degrees, the calculation would be:

PRA = 30 + 40 – 20 = 50 degrees

Thus, the Prism Refraction Angle would be 50 degrees.
