The formula to calculate the Angle of Incidence (θ1) is:
\[ θ1 = \sin^{-1} \left( \frac{n2 \cdot \sin(θ2)}{n1} \right) \]
Where:
The Angle of Incidence is defined as the angle between the ray incident on a surface and the line perpendicular to the surface.
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.
