"Reflections"

Reflections occur when light waves bounce off a surface, changing direction while maintaining their speed and wavelength. This process explains how we see objects: light hits an object, reflects off its surface, and travels to our eyes. The angle at which light hits a surface, called the angle of incidence, equals the angle at which it reflects, known as the angle of reflection, following the law of reflection. Reflections can be clear and mirror-like or scattered and diffuse, depending on the surface's smoothness. This phenomenon is fundamental to optics, enabling devices like mirrors, telescopes, and cameras.
