Light Reflection
Light reflection is the bouncing back of light waves when they hit a surface. In geometrical optics, this is described by two key principles: the angle of incidence (the angle at which incoming light strikes a surface) is equal to the angle of reflection (the angle at which light bounces away). This behavior enables us to see objects, as light reflecting off their surfaces enters our eyes. Mirrors, for example, are designed to reflect light efficiently, allowing us to see clear images. Understanding reflection helps us design optical devices and enhances our ability to utilize light in everyday life.

Light reflection is the bouncing back of light rays when they encounter a surface. This occurs because different materials have varying properties; smooth, shiny surfaces like mirrors reflect light clearly, while rough surfaces scatter light in many directions. When light hits a surface, the angle at which it strikes (the angle of incidence) equals the angle at which it bounces off (the angle of reflection). This phenomenon is why we can see our image in a mirror or why objects appear bright when light hits them. Reflection is fundamental to vision and plays a crucial role in how we perceive our surroundings.
