Law of Reflection: The angle of reflection equals the angle of incidence.

Key Points:k

1. Both angles are measured from the normal (perpendicular to the surface)
2. The incident ray, reflected ray, and normal all lie in the same plane
3. This law applies to all types of reflection

Mathematical Relationship:

$\theta_r = \theta_i$

📊 Example Data:

💡 Note: This fundamental law forms the basis for understanding mirrors, periscopes, and many optical instruments used in physics.
