Difference between real and virtual image

What is the difference between Real and Virtual Images?

Difference between the virtual and real image

A real image and a virtual image are different image formats. The main difference between real and virtual images is in the way they are created. A real image is formed when the rays meet, while a virtual image is formed when the rays are only seen moving. Let's take a closer look at the difference between real images and virtual images in this article.

The light source and the screen must be on the same plane to get the original image. The image is obtained using a converging lens or a concave mirror. The size of the image depends on the location of the object.

A virtual image, on the other hand, is a simple image that can be obtained where the rays appear to be moving but do not actually meet. This image can be taken using a diving lens or a convex mirror.

Real Vs Virtual Image

So we can say that the difference between real and virtual images is that real images can be obtained on screen whereas virtual images cannot be obtained on the screen.

There was a difference between the real picture and the virtual image.

What is an Image in Physics?

Do you know what a mirror is? no! When the rays of light from an object appear to meet at a point after reflection or disturbance, that point can be described as an image. The word object in definition can be anything that emits rays of light.

An image is formed when light emanates from an object in different directions. Some of these rays that represent light reach the surface of the mirror and are reflected from the surface according to the laws of reflection.

There are two types of formatted images:

• Real Image

• Virtual Image

Do you know the meaning of these pictures and how they differ?

This page will help us to understand the different types of images formed on the mirror with their distinction.

What is an image?

Basically, a picture is a visual representation of something that is placed somewhere in front of a mirror or mirror. The formation of an image is the result of the meeting of light rays after reflection or deviation according to their respective laws.

It should be noted that the rays do not always meet each other, sometimes only appear to meet. It also produces images. Therefore, images are classified as real and virtual, depending on whether the rays meet or appear to be real. Since the two types of images are produced differently, there are different factors that we will discuss in this document.

Definition of Real Image

Real images are the type of images that are formed by the reflection of a ray of light into a point after being reflected or reflected in a mirror or mirror. Real images are formed where the rays of light interact with each other. Original images are reversed in nature and can be viewed on the screen.

Suppose an object is placed in front of a concave mirror and the light hits the surface of the concave mirror after being reflected from the object. When several rays of light collide with a mirror, following the laws of reflection, the different rays of light are reflected again and converge in one place in front of the mirror.

As we can see here, the rays of light are actually concentrated in a particular place. And at this particular position, a visible image of the object is formed. Keep in mind that once connected to a point, the rays move away from that particular point.

Definition of Virtual Image

Virtual images are images that form in a single position behind a mirror. However, in reality, the image does not exist there. Unlike real images, a virtual image is formed when the rays of reflected light are different. In this case, when the light of an object is allowed to hit the mirror and when the rays of light are reflected from the mirror, it appears that the rays are moving behind the mirror.

Basically, no light reaches the back of the mirror, so it is said that the rays always meet somewhere, because it is only the viewer's mind. This is why virtual images do not appear on the screen. Images taken in the form of airplane mirrors are usually virtual.

Another important point to note here is that virtual images are not imaginary. Thus, it has a specific shape and size and therefore can be seen with the eye or any other visual device.

Real and Virtual Images: Differences using Concave/Convex Mirrors

Now we understand what real and virtual images are:

Real Image

The sum of the focal points of a ray of light emitted from an object is described as an image in terms of optics. The classification of focal points created by converging rays is called a real image, while the combination of focal points created by the extension of different rays is called a virtual image. Simply put, an image is a real image in a plane of harmony of the rays of light emitted from an object.

When the rays meet, a real image is formed, and when the rays appear to be moving, a virtual image is formed. With the use of concave mirrors and converging lenses, a realistic image can be created, but only if the object is kept away from the focal point of the mirror, and the original image is reversed. As the object approaches the focal point, the image moves to infinity, and as the object passes through the focal point, the image becomes virtual and straight. Space is not the same from anything to glasses.

When light rays are reflected or found somewhere after reflection, they are actually present, that is, a real image can be placed on the screen. The backward extension of the reflected or reflected light rays is valid for the virtual image. That is to say, it does not really exist.

For a convex lens, placing an object equal to or less than the focal length will give you a realistic picture. This is exactly what you would find with a concave mirror, except when placed at or below the focal point. You will get a real picture.

According to the diagram below, a real image is formed by a convex lens, and a real image is formed by a concave mirror.

Example of Real Image

The most common example of a real picture is a picture on a movie screen because something is projected onto the screen using a projector. It reflects the image on the screen, which moves the object drawn by the human eye. The image is taken on a sensor on the back of the camera or on the retina of the eyeball (they focus light through an internally convex lens). In the diagrams below, the actual rays of light are shown as completely solid lines, or the rays of ordinary light are shown as dotted lines.

Virtual Image

A range of focal points formed by variable rays is called a real image, while focal points formed by the expansion of diverse rays are called virtual images. A virtual image is created by detecting real rays that emanate from an optical device such as a mirror or lens, up to the apparent reality of the radiation deflection. In an optical system diagram, dotted lines represent the classic virtual beam.

Because the rays do not intersect, a virtual image cannot be created on the screen, but when the rays meet in a real place, a real image can be created on the screen. People can view the image as if it were a real image being projected onto a screen that reflects a variety of images (the image on the landscape as something to be seen with the human eye).

Below is an example of a virtual image made up of a concave mirror and an aerial mirror.

Here we note the following:

• AB = is the object
• A'B' = is the Image
• OX - is the distance of the image from the mirror
• OY - is the distance of the object from the mirror
• For a plane mirror, OY=OX

Hence, the distance between the image and the object is OX + OY = 2OY(as OX = OY)

Example of Virtual Image

The reflection in the mirror is the best example of a virtual image. The intersecting rays form real images, and the bending of the rays produces virtual images. Real screen images are presented, whereas virtual images cannot be two opposite lenses, convex and concave with respect to real images.

An airplane mirror creates a virtual image behind a mirror. The light from the source is only present in the mirror, even if the rays of light come from behind the mirror. In an airplane mirror, the image is not enlarged, which means that the object and the image are the same sizes, and it appears as far behind the mirror as the object is in front of the mirror.

From the text above the real and virtual images, we understand that a real image is actually a collection of focal points created by converging rays, whereas the combination of focal points created by the sinking of the rays is called a virtual image. Is. Simply put, it is an image located in the plane of harmony for the rays of light emanating from a given object.
