Normal incidence is at what angle?

Explanation:
Normal incidence means the incoming ray is perpendicular to the surface. The angle here is measured from the surface itself, so a line perpendicular to the surface forms a 90-degree angle with that surface. If you instead measure from the normal (a different, common convention), normal incidence would be 0 degrees, but this item uses the surface-based convention, making 90 degrees the correct interpretation.
