Question

what do you mean by real image and virtual image


and answer is long no short​

Answer 1

Answer:

In optics, an image is defined as the collection of focus points of light rays coming from an object. A real image is the collection of focus points actually made by converging rays, while a virtual image is the collection of focus points made by extensions of diverging rays. In other words, it is an image which is located in the plane of convergence for the light rays that originate from a given object. Examples of real images include an image on a cinema screen (the source being the projector, and the screen plays as a diffusely reflecting surface so the image formed on the screen plays as an object to be imaged by human eyes), the image produced on a detector in the rear of a camera, and the image produced on an eyeball retina (the camera and eye focus light through an internal convex lens

Answer 2

Answer

• A real image is the collection of focus points actually made by converging rays, while a virtual image is the collection of focus points made by extensions of diverging rays. ... A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge.
• an image (such as one seen in a plane mirror) formed of points from which divergent rays (as of light) seem to emanate without actually doing so
