What is Optics? Photonics?
... • Think of optics as the science of light. It’s a branch of physics that describes the behavior and properties of light and the interaction of light with matter. It’s about what light is made of and how it behaves. • Light allows us to see, but it also transmits sound, cuts things, and controls elec ...

Mirrors form images by reflecting light.
... see how the light waves create images inside the human eye. Light rays bounce off objects in a very predictable way. For example, look at the diagram on the left below. Light rays from a flashlight strike a mirror at an angle of 60° as measured from the normal, an imaginary line perpendicular to the ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
