Albedo is the fraction of solar energy (shortwave radiation) reflected from the Earth back into space.
The albedo of an object is a measure of how strongly it reflects light from light sources such as the sun. It is therefore a more specific form of the term reflectivity.
The distance between the surface at the center of a reflective surface and its focal point is equal to half the radius of curvature of the surface.
Mirrors are backed with silver because it is an excellent reflector of light. Silver provides a clear and reflective surface that creates a high-quality image for viewing. Additionally, silver is resistant to corrosion, making it ideal for long-lasting mirrors.
The term you are referring to is the focal length, which is the distance between the surface of a reflective surface (such as a mirror) and the focal point.
A chalkboard has matte surface, which is non-reflective and not shiny.
It reflects with the angle of incidence (angle between the original ray of light and the normal (90 degrees to the mirror surface)) being the same as the angle of reflection (angle between the reflected ray of light and the normal). Some of the light energy is transferred into heat energy by the mirror, so the reflected beam is less bright than the original beam, but the difference is barely noticeable on a clean mirror.

A good reflective surface should have high reflectivity, meaning it effectively bounces back light rather than absorbing it. It should also be smooth and polished to minimize scattering and ensure a clear image. Additionally, the surface material should be durable and resistant to environmental factors like corrosion or scratches, maintaining its reflective quality over time. Finally, the color of the surface can influence its effectiveness, with lighter shades typically reflecting more light.
The imaginary line that extends straight out from the center of a reflective surface is the optical axis.

Yes, a shiny plate of metal can be considered a mirror if its surface is smooth enough to reflect light clearly. Mirrors typically have a reflective surface that allows them to produce a clear image, and polished metal can achieve this quality. However, the effectiveness of the metal as a mirror depends on its finish and the quality of the surface.
