Virtual and real image of mirror?

Question

Give me a practical example of Virtual and real image .

Answer 1

yes sir

Answer 2

Go to a funhouse. Look in any mirror. If your image is upside-down, it is a real image, and if it is right side up it is a virtual image.

This is because of the geometry of how the light rays bounce off of concave (real image) or convex (virtual image) surfaces.

If you get too close to the concave mirror, your image blows up, distorts, and then you see a virtual (right side up) image. You are now between the mirror and its front focus.

Since a flat mirror has a focus at "infinity" behind you, you are always between the mirror and its focus--therefore the image in a flat mirror is also a virtual image.

Interestingly, the apparent "focus" of a convex mirror is behind the mirror, but elementary geometry tells you it would have to be "behind" the focus of a flat mirror. So in some sense, going "beyond infinity" puts the point behind the mirror.

Actually you don't have to go to a funhouse--you can probably do most of this with a cosmetics mirror.

You can also get real and virtual images with a magnifying glass. If you hold the lens at arm's length, and look at distant objects, you'll see them upside-down and, apparently, in front of the lens. These are real images--the light actually diverges from the points it seems to. If you put the lens up close to something, the image will be right side up and appear to be behind the lens. This is a virtual image.

Answer 3

Convex Mirror creats Virtual images while Concave mirror creats real or true images.
An image that appears to be in front of the mirror is usually real. An image that seems to be behind the mirror is virtual.
The light does not go behind the mirror. A real image can be used to expose film, creating a photograph. This cannot be done with a virtual image. To use a virtual image for this, you must use a lens or another mirror to create a real image on the film.

Answer 4

Well, I can give you an example of what one is. A real image is basically a projection off of a mirror, so the type that work best for creating a real image are concave mirrors. The light converges at a point, and if you hold an object at that point, such as a white board, you will see the object, in focus, on the white board. The practicallity of this is endless, as it is used in projectors (where the light is focused through a one sided convex lens instead of a concave mirror) and things of that variety.

The virtual image, on the other hand, is the object you "See on the other side" So if you were looking at a mirror, it's the object you see "inside" of the mirror, and if you are looking through a lens, it's the object you see "inside" of the lens. The practicality of these are also nearly limitless, from things such as changing camera angles through the use of different lenses to something so normal as looking at yourself in the mirror when you wake up in the morning.

Answer 5

"In optics, a virtual image is a representation of an actual object (source) formed by diverging rays of light which seem to originate from the image, but in reality do not come from that position. A screen or an observer placed where a virtual image appears to be cannot actually "see" it.

"In optics, a real image is a representation of an actual object (source) formed by rays of light passing through the image. If a screen is placed in the plane of a real image it will generally become visible.

Real images can be produced by concave mirrors and converging lenses."

For example, a plane or convex mirror forms a virtual image positioned behind the mirror. Although rays of light seem to come from behind the mirror, light from the source spreads and exists only in front of the mirror."

Answer 6

In a plane mirror you see yourself "behind" the mirror even though you are not really there - it is a "virtual" image.
If you use a concave mirror to reflect the image of the sun to burn something then the image of the sun is "really" where the burning takes place - a "real" image.
You can reflect real images onto a screen but not a virtual image.

Answer 7

Virtual image would be your reflection (it's not reality).

A real image would be a reflection of a reflection.

Just my first hit on this answer; I don't know much about physics.

Answer 8

Images created by both mirrors & lenses

Real image in mirrors:
-----------------------------
a) in concave mirror when:
- 2 rays come from the same point from very far object (infinity > 6 meters)
- object beyond center of curvature
- object at the center of curvature
- object between focus & center of curvature

Virtual image in mirrors:
------------------------------...
a) in concave mirror when:
- object anywhere between the focus & the pole of the mirror
b) in canvex mirror when:
- object anywhere on the principle axis

Real image in lenses:
----------------------------
a) in convex lens when:
- 2 rays from the same point from a very far object (infinity)
- object at a distance bigger than double the focal length
- object at distance equal double the focal length
- object at a distance bigger than the focal length but smaller than double the focal length

Virtual image in lenses:
------------------------------
a) in convex lens when:
- object is anywhere between the lens & the focus
b) in concave lens when:
- object is anywhere on the principle axis

u can see the prove of any case of these cases that i mentioned above by drawing the figure of the lens (or mirror) with the position of the object, focus, etc .... & u will find out how real & virtual images created

i hope u got ur point from my explanation

Answer 9

i am sulin and i am not myself
i am her...
Her...the person i see in the mirror everyday
downside up, outside in
the world is the actual reflection.
the surreal is the real.
what i see is what she dreams

I only survive thinking i was not a bogus
I live in between two mirrors...
in which i see many hers...
each one think the rest are images

Strangely...,
I am "ME" for every she....

Answer 10

John (fictitious name) assumed that his hand was real. He could see it. If he gave someone the finger, they could see it. If he touched something with his hand, he could feel the something and he could feel his hand feeling. If he touched something stinky, he could smell it on his hand. etc. etc.

Then one day he read that everything he saw was an image on the visual cortex of his brain. "Whoa!" he exclaimed. "This is really wierd! Looks like it's out there but it's really behind my eyes! Except I can feel it." Then it occurred to him that his sense of touch also fed into his brain, as did all of his senses.

"Wow!" he thought. "My brain is like the holodeck on Star Trek! How am I supposed to know what's virtual and what's real?"

And a little voice (God knows if it was virtual or real) replied, "You can't."

Answer 11

The image in the mirror is atomic.
