what is meant by vertual
images and real images give two examples
Answers
Explanation:
A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge. Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point, and this real image is inverted.
The best example of a virtual image is your reflection in the mirror.
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
Answer:
Real image is formed by the actual intersection of light rays. It can be obtained on a screen. Hence, projectors form real images.
Virtual image is formed when the light rays appear to be originating from a point but does not actually meet. It can be seen by human eyes. Hence, rear-view mirrors form virtual images.
