Calculate Angle of Incidence





Formula

The formula to calculate the Angle of Incidence (θ1) is:

\[ θ1 = \sin^{-1} \left( \frac{n2 \cdot \sin(θ2)}{n1} \right) \]

Where:

What is the Angle of Incidence?

The Angle of Incidence is defined as the angle between the ray incident on a surface and the line perpendicular to the surface.

Example Calculation

Let's consider an example:

Using the formula to calculate the Angle of Incidence:

\[ θ1 = \sin^{-1} \left( \frac{1.33 \cdot \sin(30)}{1.5} \right) \approx 26.32 \text{ degrees} \]

This means that the angle of incidence for this example is approximately 26.32degrees.
