In our daily work, we often encounter inquiries that need self-cultivation glasses, and some clothing sales, especially women's clothing sales, are particularly prominent. What kind of mirror image will be thin and what is the principle of thinness?
The so-called ultra-thin mirror uses the principle of optical refraction. Anyone who has studied physics knows that when the mirror has a certain curvature, the imaging will be distorted. When the mirror is concave, it looks thin, and when it is convex, it looks fat.
Just like the mirror I took when I was a child, some were fat and some were thin. Therefore, the thin mirror is concave mirror, and the degree of thinness depends entirely on the concavity.
In real life, we usually use a flat and smooth mirror. We'd better choose to use slender oval and rectangular mirrors, the width of which is within 60 cm and the length is 3-4 times of the width, so that the imaging effect will visually feel that people are elongated and appear slender. More visual impact.
