Can the cosmetic mirror fire?

Most hotels are equipped with magnifying mirrors. Through direct visual observation, the whole face or mirror image is enlarged. If you carefully observe the pores of the skin, you can see the hair more clearly. This is a magnifying mirror.

On the reverse side is an ordinary mirror, with a stretchable bracket, and there are also standing cosmetic mirrors on the market. In the same way, it is easy to judge by direct visual inspection.

If it's for makeup, an ordinary mirror is actually enough. If better, you can control the light, and then use electroluminescence on the top of the mirror and warm light on both sides of the mirror. This can produce very natural light. Many star dressing rooms are arranged as a cross between electroluminescence and warm light. If the light is completely cold, such as fluorescent lamps, the makeup will not be full, and if it is completely warm, it may lead to too much makeup. Telescope is an optical instrument that uses optical devices such as lenses or mirrors to observe distant objects.

The light passing through the lens is refracted or reflected by concave mirror into the pinhole to converge and image, and then it is seen through the magnifying eyepiece.

A convex lens can be used, but a concave lens can't, because the convex lens is thick in the middle and thin in the round side, so that the light can be focused into a point and things can be ignited. The concave lens is concave, which has no great effect and does not allow fire.

Also known as "a thousand-mile mirror". The first function of the telescope is to enlarge the opening angle of distant objects, so that the human eye can see the details with smaller angular distance. The second function of the telescope is to send the light beam collected by the objective lens, which is much thicker than the pupil diameter (up to 8 mm), to the human eye, so that the observer can see dim objects that he could not see before.
