"Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated."
Study of the reflection of light from surfaces and mirrors.
Optics Basics: This includes the fundamental concepts of optics such as light, refraction, reflection, lenses, and mirrors.
Reflection and Refraction: This topic explores the principles of reflection and refraction of light, which are essential in reflective optics.
Lens Equation: The lens equation helps to determine the relationship between the object distance, image distance, and focal length of a lens, which is important in reflective optics.

Mirrors: A smooth surface that reflects light.
Prisms: A glass or plastic object with at least two polished flat sides that reflect light.
Reflective Lenses: A lens designed to reflect light back towards its source.
Retro-Reflectors: A device that reflects light back towards its source, regardless of the incoming angle, by using multiple reflective surfaces.
Corner Reflectors: A type of retro-reflector, typically made of three flat surfaces arranged at 90-degree angles to one another.
Hollow Retro-Reflectors: A type of retro-reflector consisting of a hollow metal or glass cube with three mutually perpendicular mirrors with reflective surfaces on the inside.
Reflective Films: A thin sheet or layer of reflective material, such as aluminum, applied to a surface.
Reflective Paints: A coating of paint or other material that reflects light.
Reflective Fabrics: A fabric treated with a reflective coating or woven with reflective fibers to enhance visibility.
Reflective Tiles: Tiles with a reflective surface that can be used for decorative or functional purposes.
"Common examples include the reflection of light, sound, and water waves."
"The law of reflection says that for specular reflection (for example at a mirror) the angle at which the wave is incident on the surface equals the angle at which it is reflected."
