Imaging characteristics of convex lens and concave lens What are the imaging characteristics of convex lens and concave lens?

1. If you want to know the imaging characteristics of convex lens and concave lens, you must know what they are. A convex lens is also called a positive spherical lens, with a thick middle and a thin convex edge, which can condense light, and a concave lens is also called a negative spherical lens, with a thin concave edge in the middle, which can disperse light.

2. The convex lens is refractive imaging, such as inverted image, reduced real image, inverted image, equal real image, inverted image and enlarged real image. The imaging law of concave lens is that when the object is solid, it becomes an upright and reduced virtual image, and the image and the object are on the same side of the lens.

3. Many daily necessities in our life use the imaging characteristics of convex lens and concave lens, such as cameras, video cameras, projectors, movies, magnifying glasses and so on. Concave-convex lenses are mainly used for myopia glasses, desk lamps, radars, flashlights, etc.
