In an amusement park maze with all the walls covered with mirrors, Pilar sees Hernando's reflection from a series of three mirrors. If the reflected angle from mirror 3 is $55^{\circ}$ for the mirror arrangement shown in the figure, what is the angle of incidence on mirror $1 ?$ (FIGURE CAN'T COPY)

Key Concepts

Multiple Mirror Reflections

In systems with several mirrors, the process of reflection is applied sequentially at each mirror. Each reflection alters the light’s direction according to the law of reflection. Analyzing such systems requires understanding how successive reflections interact to produce the final path of the light ray.

Geometric Transformation in Mirror Systems

Mirror reflections can be seen as geometric transformations that change the orientation of images. In complex mirror arrangements, such as in a maze with multiple mirrors, these transformations cumulatively affect the direction of the reflected ray. Understanding these transformations is key to solving problems involving angles of incidence and reflection in multi-mirror setups.

Law of Reflection

The law of reflection is a core concept in optics stating that the angle of incidence is equal to the angle of reflection when light strikes a reflective surface. This principle is fundamental for understanding how light behaves when it reflects off a mirror, regardless of the mirror’s orientation.
