Reflection of light refers to the process by which light waves bounce off a surface, changing direction without being absorbed. When light strikes a surface, it can be absorbed, transmitted, or reflected. Reflection occurs when light waves hit a surface and are bounced back in a new direction. The angle at which the light hits the surface, known as the angle of incidence, is equal to the angle at which it is reflected, known as the angle of reflection.
This phenomenon is the basis for how we see objects around us. When light from an object reflects off its surface, it enters our eyes and is detected by our retina, which sends signals to our brain that allow us to see the object. Reflection is also what allows us to see our own reflection in a mirror or other shiny surface. The smooth surface of the mirror reflects the light rays, allowing us to see an image of ourselves or whatever is in front of the mirror. Reflection is used in many areas of science and technology, including optics, photography, and engineering.
