Final answer:
Reflexive pronouns 'reflect' back to the same person or thing, and in physics, the law of reflection states that the angle of reflection equals the angle of incidence. This concept is crucial in understanding how light behaves and is applied in various situations like mirrors and telescopes.
Step-by-step explanation:
Reflexive pronouns are pronouns that 'reflect' back to the same person or thing. In physics, the concept of reflection is seen in the law of reflection, which states that the angle of reflection equals the angle of incidence. This law applies to various situations, such as when light rays bounce off a mirror or when telescopes use reflection to form images. Understanding the concept of reflection is important in physics for studying optics and understanding how light behaves.
