Optical Properties Of Cosmetic Mirrors

- Sep 29, 2018-

Specular reflection of the light obeys the law of reflection. The reflective ability depends on the angle of the incident light, the smoothness of the mirror and the properties of the metal film being plated. The imaginary line perpendicular to the mirror is called the normal, and the angle between the incoming ray and the normal and the reflection line are equal to the angle of the normal. The object in front of the plane mirror is virtual image in the mirror, as the distance from the mirror is equal to the distance between the object and the mirror. If you want to see my whole length from the mirror, the mirror must have at least half of my length as the angle of incidence equals the reflection angle. The reflective surface of the concave mirror toward the center of curvature. The parallel ray incident to the concave mirror reflected after the focus (f), the focus position at the curvature Center (c) and the mirror distance of 1/2. such as the cooking device placed in the focus of the large concave mirror, can accept sunlight gathered heating, become a solar stove. If the light source in the lamp or searchlight is placed in the concave mirror focus position, the light reflects the parallel light. objects can be reflected as inverted real image, such as reflective telescopes, outside the center of curvature. Convex mirror the reflective surface of the center of curvature, the object in the mirror into a shrinking positive image, can reflect a wide range of narrow landscape, such as car rearview mirror
