Optical Properties Of Mirrors
- Oct 30, 2017 -
Specular reflection obeys the law of reflection on light. Its reflective ability depends on the angle of the incident light, the smoothness of the mirror and the properties of the metal film. The imaginary line perpendicular to the mirror is called the normal, and the angle between the ray and the normal is equal to the angle of the line and the normal. The object in front of the plane mirror is virtual, like the distance from the mirror and the distance of the object from the mirror. If you want to see the whole length of the mirror, because the angle of incidence is equal to the reflection angle, the mirror must have at least half of my height. The concave reflector faces toward the center of curvature. The parallel light incident to the concave reflex is clustered to focus (f), focusing on the center of Curvature (c) at 1/2 Point distance from the mirror. If the cooker is placed in a large concave focus position, the sun can be heated and become a solar cooker. A light or searchlight, such as a light source placed in a concave focus position, can reflect a parallel light. Objects outside the center of curvature can be reflected as inverted real, such as reflective telescopes. The reflective surface of the convex is the center of curvature, the image of the object being reduced in the mirror, reflecting a wide range of narrow landscape, such as car rearview mirror
