concave convex的用法详解
The Words \"Concave\" and \"Convex\"
The English words \"concave\" and \"convex\" are often used to describe the shape of different surfaces. Concave surfaces are curved inward, like an indented bowl, while convex surfaces are curved outward, like the surface of an inflated balloon.
A good example of a concave surface is the inside of a spherical glass bowl or a spherical mirror. In this case, the surface is curved inward and objects that are placed close to the center of the bowl will be magnified. Similarly, a convex surface, like the surface of a balloon, curves outward and objects that are placed near the center of the surface will be reduced in size.
The terms \"concave\" and \"convex\" are also used to describe the shape of lenses. In this case, a concave lens is curved outward and acts as a magnifying glass to make objects look bigger. Similarly, a convex lens is curved inward and acts as a reducing glass to make objects look smaller.
The words \"concave\" and \"convex\" can also be used to describe the shape of curved surfaces that are not necessarily spherical. In this case, a concave surface is curved inward and a convex surface is curved outward.
Finally, the terms \"concave\" and \"convex\" can be used to describe other shapes, such as the surface of a saddle. In this case, a concave surface is curved inward, like the seat of a saddle, and a convex surface is curved outward, like the handlebar of a bicycle.
In summary, the words \"concave\" and \"convex\" are used to describe surfaces that are curved inward or outward. Concave surfaces are curved inward, like the inside of a bowl, and convex surfaces are curved outward, like the surface of a balloon. The terms are also used to describe the shape of lenses and other curved surfaces, such as the surface of a saddle.
