Optical Properties Of Cosmetic Mirror

The reflection of a mirror to light is governed by the law of reflection. Its reflection ability depends on the Angle of the incident ray, the smoothness of the mirror and the nature of the coated metal film. An imaginary line perpendicular to the mirror is called a normal, and the Angle between the incoming ray and the normal is equal to that between the reflected ray and the normal. The object in front of the plane mirror becomes a positive virtual image behind the mirror. The distance between the image and the mirror is equal to the distance between the object and the mirror. If you want to see your entire length in the mirror, since the Angle of incidence is equal to the Angle of reflection, the mirror must have at least half of your length. The reflecting surface of a concave mirror is oriented toward the center of curvature. The parallel rays incident on the concave mirror reflect and converge to the focal point (f), the focal point being 1/2 the distance from the center of curvature (c) to the mirror. If the cooker is placed in the focal point of the large concave mirror, it can accept the concentrated heat of sunlight and become a solar oven. If the light source in the car lamp or searchlight is placed in the focal position of the concave mirror, the light can reflect out parallel light. An inverted real image of an object, such as a reflecting telescope, that is reflected away from the center of curvature. A convex mirror has a reflective surface facing away from the center of curvature. The object behind the mirror becomes a reduced upright image, which can reflect a wide range of reduced landscapes, such as a car rearview mirror
