A ray of light is reflected from two mirrored surfaces as shown in the figure. If the initial angle of incidence is $34^{\circ}$, what are the values of angles $\alpha$ and $\beta$ ? (The figure is not to scale.)

Key Concepts

Law of Reflection

This fundamental principle states that when a light ray strikes a mirror, the angle at which it arrives (the angle of incidence) is equal to the angle at which it leaves (the angle of reflection). This law is key to analyzing how light behaves when it bounces off surfaces, regardless of the orientation of those surfaces.

Ray Diagram Analysis

Using ray diagrams allows us to visually represent the path of light as it undergoes reflections. By drawing the normals to the mirror surfaces and marking equal angles of incidence and reflection, one can systematically determine unknown angles in multi-reflection scenarios without relying on specific numerical examples.

Multiple Reflection Geometry

When light reflects off multiple surfaces, each reflection adheres to the law of reflection, and the overall path is determined by the geometric relationships between the mirrors. Understanding how to apply geometric reasoning in composed reflection events is key to solving for unknown angles in such systems.
