can a virtual image be photographed by a camera . Pls explain briefly to understand easily.
Answers
When a simple lens creates an image it does it in one of two basic ways. It either creates a real image or a virtual image.
If the rays of light produced by an object go through a lens and are refracted so that they actually cross on the far side of the lens, those rays will produce a real image. This is called a "real" image because the rays produce a visible image at the point where the rays cross. That means if you place a piece of paper or the film (or image detector of digital camera) at that point you will be able to see the image of the object. Therefore, you can in fact take a picture of a real image.
If the rays of light produced by an object go through the lens and are refracted in such a was that they do not cross on the far side of the lens, then they can not form an image. If you move your eye to the far side of the lens and look back through the lens toward the object you will see an image. This image is called a virtual image. It is not created by the actual crossing of light rays. It looks like they are coming from the object side of the lens because your brain assumes the rays are coming from that location even though they aren't. If you were to place a piece of paper or film at the place where you believe the image to be, there will be no image produced on the paper or film. So, if you try to take a picture of the virtual image by placing the camera where the image appears to be you will not be able to take a picture of the virtual image. On the other hand, if you move the camera to the far side of the lens and take a picture back through the lens, toward the object you will be able to take a picture of the lens system including the virtual image.
However, you should keep in mind that when you take a picture of a virtual image you are not actually taking the picture of something that is really there.
Yes, a camera can photograph a virtual image. That's because the luminous rays that emit from such a virtual image and enter the camera lens are actual.
Explanation:
- Yes, a camera can photograph a virtual image. That's because the luminous rays that emit from such a virtual image and enter the camera lens are actual.
- After reflecting actual incident rays, a simulated image is created from a reflecting surface so that these rays reach the camera to offer effects on the photographic film. Much like we can see a simulated picture in a mirror through our eyes, so can a camera capture it.

A virtual image, we always say, cannot be caught on a screen. Yet when we ‘see’ a virtual image, we are obviously bringing it on to the ‘screen’ (i.e., the retina) of our eye. Is there a contradiction?
