Reflection can be studied both with a beam that initially propagates in air (first medium) and is reflected in a mirror (second medium) and in a beam that propagates in glass (first medium) and is reflected in an edge covered by a layer of metal that turns it into a mirror (second medium).

In both cases it is observed that the angle of incidence is identical to that of reflection.

Not being able to perceive the refraction of the beam, objects under water are perceived in a different place than they actually are.

If the beam in a medium of less speed tries to move to a medium of greater speed in an angle such that there is no refractive angle this is fully reflected in the interface between both means.

Description

If two angles are at an angle less than 90 degrees a beam that is reflected in one of these will reach the second.

Concept

>Top

If you think of light as particles (photon) that affects a non-transparent body, it is reflected.

The reflection occurs so that the angle of insidence is equal to the angle of reflection.

On the other hand, the photons do not change in frequency or wavelength, that is, they only suffer a change in the direction of propagation with respect to the plane of impact.

A mirror looks like a window to another room. The effect is created by the reflected light that the eye assumes was not reflected but comes from an object behind the mirror.
