What is the degree of reflection of light from sun to the moon? As Moon reflects the light from the sun it must have an ANGLE OF INCIDENCE and ANGLE OF REFLECTION...
What Is the angle of reflection then?
Basically, the sunlight is reflected from the Moon at different angles. It works the same as on Earth. For instance, during the sunrise &amp; sunset, the sunlight is reflected at a bit above 0 degrees angle, whereas at the noon in the tropical areas (in general) where Sun passes the zenith, the sunlight is reflected at 90 degrees. On Moon and other planets, it works exactly the same! This is how the angle of reflection works. Obviously, because we have a rough surface built with different rocks, we can't treat the celestial body as a mirror. However, the phenomenon is analog, as each of them has its own albedo - ability to reflect the light. Lunar albedo is 10%.

Obviously, it's worth mentioning that as the angle of light reflection is smaller, then the light beam is weaker (less intensive). It arises out of the inverse square law:

which can be explained by the image above.
The angle of incidence is always equal to the angle of reflection, but it's perpendicular to the surface exactly, where the beam hits this surface.

Otherworldly, the angle of incidence is related to the plane of incidence. The plane of incidence is the &quot;place&quot; where an observer can see the reflected solar beam on the surface.
Along with the angle of incidence, we can mention the light glitters produced when our angle of reflection is low enough.
