What is real and virtual image, give some normal example?

virtual image-cannot be obtained on a screen always erect formed by diverging light rays in which they do not intersect real image-can be obtained on a screen always inverted formed by converging light rays that actually intersect

virtual image is the one which cannot be obtained on screen and real image is the one which can be obtained on screen.

A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to converge. Real images can be produced by concave mirrors and converging lenses if and only if the object is placed further away from the mirror/lens than the focal point and this real image is inverted.I'll steal some image from Wikipedia to help here:First consider the line optics of real images (from http://en.wikipedia.org/wiki/Real_image): Notice that the lines that converge to form the image point are all drawn solid. This means that there are actual rays, composed of photon originating at the source objects. If you put a screen in the focal plane, light reflected from the object will converge on the screen and you'll get a luminous image (as in a cinema or a overhead projector).Next examine the situation for virtual images (from http://en.wikipedia.org/wiki/Virtual_image): Notice here that the image is formed by a one or more dashed lines (possibly with some solid lines). The dashed lines are draw off the back of solid lines and represent the apparent path of light rays from the image to the optical surface, but no light from the object ever moves along those paths. This light energy from the object is dispersed, not collected and can not be projected onto a screen. There is still a "image" there, because those dispersed rays all appear to be coming from the image. Thus, a suitable detector (like your eye) can "see" the image, but it can not be projected onto a screen.Now for the example:Operationally, one can distinguish real and virtual images by attaching a small but very powerful light bulb to the source.If you insert your hand near the real image, the hand will get burned because the light rays from the source actually converge at the point of the real image. If you manage to insert your hand to the point of the virtual image, your hand won't burn because there are no light rays over there (and sometimes, there is a wall).An ordinary flat mirror creates a virtual image because there are no light rays on the internal side of the mirror.The optics in the human eye creates a real image where the retina is located and sensitive cells actually read the information about the original source. The same mechanism works in digital cameras.Real images may be produced by converging lenses (eye, digital camera) and concave mirrors.Virtual images may be produced by diverging lenses and convex mirrors, but also by concave mirrors and converging lenses if you place the source within the focal length.

A real image is one that light passes through.  Focus an image of the sun on a piece of paper, and that will be a real image. A virtual image is one that the light does not pass through. Simplest example: your image in a mirror.

Normal examples. Here we go: 1. For virtual image, look at the following image The image formed in the plane mirror is always virtual i.e., image forms in virtual world and hence virtual image. You can not touch this image. But still the image exists. Now look at the following ray diagram: As you can see, the ray of light after reflection from the mirror does not "penetrate" through mirror but get reflected. The reflected rays of light is "diverging" i.e., they expand as they proceed. However, when a viewer look at those diverging rays of light, it "appears" to him as if this rays are coming from "somewhere". That "somewhere" is your virtual image. 2. For real image, look at the following image: It is a typical diagram of a projector, which you must have seen somewhere in your school or class. You insert a slide and then you are able to see an image on the screen. Such an image, which can be observed on a screen is called Real image, because it actually exists in your real world. In short, virtual images can't be observed on a screen (like the one you see in mirror) but real images can be observed on screen (like the one you see in Cinema Halls) I hope I'm clear to you now. Let me know through comments.

I'd prefer if you gave some clear context for your question. In Physics, The real-life reflections you see in bathroom mirrors are virtual images. On the other hand, if you have ever used a camera,still or video, the image formed is a real image. Images formed in our own retinas(part of our eyes) are real images.

Real images are the images which are formed on the back side of mirror and virtual images are the images which are formed on the front side of mirror. Confused? See these images: Hope this helps and do correct me if I'm wrong.

Real image is what can be seen with eyes, seen on screen, or could be shot by camera. In short, the images which can be projected are real images.Cinema theatre could be a good example of real image.Virtual images are the ones which cannot be projected over a screen.Apart from the image in plane mirror, image from magnifying glass, or in a shaving mirror are examples of virtual image.

The real image is the one that painted on canvas, concrete, wood , whatever. The virtual image is the photograph, analog or digital,  if  that original painting  or drawing that was on paper or canvas at  one time. Being able to see "through" some thing is what determines whether an image is "real," analog  or virtual..  This picture, image of part of Bryce Canyon, i  virtual.  it you want hike IN  The real Bryce Canyon , You might be able toi. Depending on the Department of the Interior and Park Service regulations. Those are "real" rocks that you can TOUCH. They are tangible and "real" but the image  is virtual. Pleases, skip the debate about if it is intangible  is real or  is it a delusion. Intangible think are VERY real.
