A. It can form a real image. B. It can form a virtual image. C. It always makes objects appear smaller. D. It can focus light. 相关知识点: 试题来源: 解析 C。凹面镜可以形成实像和虚像,也能聚焦光线,选项 A、B、D 正确;凹面镜不一定总是使物体看起来更小,有时也能放大物体,所以选项...
It means the image that forms by a plane mirror is a virtual image. So it is not possible to have a real image of a real object formed by a convex mirror. Step 3: In the case of a concave mirror, A concave mirror formed a real image when the object is located at a distance g...
Plane mirrors and convex mirrors always form a virtual image of an object.
The present invention relates to a concave mirror composed of a plurality of planar facets. According to the invention, all the facets are identical and the two dimensions of said facets are such that the square root of their product is at least approximately equal to the ratio of the focal...
What kind of image will form using a concave mirror? Concave mirrors can produceboth real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced,...
Yes, a concave mirror acts as a positive lens. The focal length of a concave mirror is positive, just like the focal length of a convex lens. There... See full answer below.Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a qu...
An optical arrangement for imaging a relatively small or slit- like surface is disclosed which includes a concave mirror or a concave grating. Astigmatism is corrected for the concave mirror or concave grating by mounting a slab waveguide at the surface which is to be imaged or at the image ...
