The face of a mirror typically has no color, it is a reflective surface.
No, a mirror is typically made out of glass with a reflective coating applied to the back surface. Sand is not translucent or reflective enough to function as a mirror.
Io, the innermost of Jupiter's four largest moons, appears the brightest from Jupiter's surface due to its proximity to the planet and its reflective surface.
Europa is the brightest moon of Jupiter because its surface is covered in smooth ice, making it highly reflective. This icy surface reflects more sunlight compared to the other moons with darker, more cratered terrains, despite being further away from Jupiter.
Like most objects in space, the Moon possesses a reflective characterisitic called albedo. Albedo is how well an object reflects light. What makes the moon so interesting is that it has the same Albedo as coal. That means that it has almost no reflective quality up close.

CDs are made from almost-pure polycarbonate plastic. A thin layer of aluminum or sometimes gold is applied to the surface to make it reflective. This in turn is protected by a lacquer film.
To effectively clean polycarbonate using alcohol, dampen a soft cloth with isopropyl alcohol and gently wipe the surface of the polycarbonate. Avoid using excessive pressure to prevent scratching the material. Repeat as needed until the surface is clean.
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.
A Compact Disc is made from a 1.2 mm thick disc of almost pure polycarbonate plastic and weighs approximately 16 grams. A thin layer of aluminum or, more rarely, gold is applied to the surface to make it reflective, and is protected by a film of lacquer. The lacquer is normally spin coated directly on top of the reflective layer. On top of that surface, the label print is applied.
Yes, gallium is used in the production of mirrors in a process called liquid metal mirror (LMM) technology. The reflective surface is made by coating a layer of liquid gallium on a mirror substrate, resulting in a highly reflective surface suitable for use in telescopes and other optical devices.
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.
The imaginary line that extends straight out from the center of a reflective surface is the optical axis.
A chalkboard has matte surface, which is non-reflective and not shiny.
The imaginary line that extends straight out from the center of a reflective surface is the optical axis.
It has a polished reflective surface.
The term that indicates an imaginary line extending straight out from the center of a reflective surface is called the "normal line." This line is perpendicular to the surface at the point of incidence where light strikes the reflective surface. It is essential in understanding the angles of incidence and reflection in optics.
