Before introducing the difference between the imaging properties of concave mirrors and convex mirrors, the concepts of concave mirrors and convex mirrors are known. Concave mirrors are reflection imaging. A mirror (including a convex mirror) is not an instrument that transmits light but is reflected back to the image, and the light follows the law of reflection. This type of mirror is called "convergence" because they tend to collect the light that strikes the surface, and the parallel incident light will be re-aggregated at the focus, also because the normal direction of each point on the surface is different and the light is different. Angle reflection. The concave mirror not only converges the parallel rays of light into the focus, but also reflects the light emitted by the focus into parallel light.
Convex mirror imaging is an optical law. Parallel rays are projected onto the convex mirror, and the reflected light will become scattered light. If it extends in the opposite direction of the reflected light to the back of the convex mirror, it can converge and intersect at one point. This is the main focus of the convex mirror (F ), is a virtual focus.
The difference between the imaging properties of concave mirror and convex mirror
The convex lens is an image formed by refraction and can be positive or negative; virtual, real; Concentration
The concave mirror is a reflection image which can be a real image or a virtual image, and can be an enlarged, equal, and reduced image.
The astigmatism lens (including the convex lens) is an instrument that transmits light and uses light to fold and image. The light obeys the law of refraction.
A mirror (including a convex mirror) is not an instrument that transmits light but is reflected back to the image, and the light follows the law of reflection.
The convex lens can be an inverted magnified, equal-sized, reduced real image or an erect magnified virtual image. Parallel light can also be concentrated to refract light from the focus into parallel light. The convex mirror can only be a virtual image that is erect and narrow, mainly for expanding the field of view.
