When you see yourself in a mirror, it appears that the image is actually behind the mirror (Figure \(\PageIndex{4}\)). We see the light coming from a direction determined by the law of reflection. The angles are such that the image is exactly the same distance behind the mirror as you stand in front of the mirror.

- 25.2: The Law of Reflection
If a ray of light could be observed approaching and reflecting off of a flat mirror, then the behavior of the light as it reflects would follow a predictable law known as the law of reflection. The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
The angle of reflection equals the angle of incidence. A mirror has a smooth surface and reflects light at specific angles. Light is diffused when it reflects from a rough surface.
23 Μαρ 2022 · The law of reflection describes the type of reflection you see from a mirror. The angle between the incident ray and the normal is the same as the angle between the reflected ray and the normal. Another name for the normal is the perpendicular line, with respect to the surface.
The angle of reflection equals the angle of incidence. A mirror has a smooth surface and reflects light at specific angles. Light is diffused when it reflects from a rough surface. Mirror images can be photographed and videotaped by instruments.
26 Ιαν 2023 · The ray which is parallel to the optical axis will meet the mirror perpendicular to its surface (or parallel to the surface normal), which means that it will reflect right back along the same line. To other two rays are shown with the incident angle equal to the reflected angle relative to the surface normal.
A surface acts as a mirror when the law of reflection is followed on a large scale, as shown in Figure 23.8 (a). In that case, the whole beam of light, with many parallel rays, reflects as expected according to the law. This is known as specular reflection: mirror-like reflection that preserves the wave-front structure.
