What Are Real And Virtual Images?

We all have mirrors at home.

And when we look at a mirror, we can see our own reflection in the mirror. That reflection is called an image.

Images are not only formed by plane mirrors. Spherical mirrors which are curved like a sphere are also capable of forming images.

When we go to the dentist, the doctor uses a spherical mirror called a concave mirror.

The images formed by this kind of mirrors are larger than the original object. As we can see the teeth appear larger in the image.

We can see this type of mirrors at intersections with traffic on the road. These mirrors are called convex mirrors.

The images formed by this kind of mirrors are smaller than the original objects.

Now let's understand the images formed by plane mirrors.

This is an image formed by the plane mirror. It looks identical to the object in shape and size.

And the image distance is the same as the object distance from the mirror.

The image formed by the plane mirror is only formed on the other side of the mirror. We say that the image is formed "behind the mirror".

Now, let us now learn about the spherical mirrors.

The images formed by the spherical mirrors are either magnified(larger than original) or diminished(smaller than original).

Magnification or diminishing depends on the position of the object with respect to the mirror.

And also, the position of the image also depends on the position of the object. It can be or

The images formed are called real images as we can catch them on a screen.

One best example of real images is the image formed by a projector on the wall or a video playing on the movie screen.

Another example of real images is the image of the sun formed by the magnifying glass.

But the images formed behind the mirror are called . We cannot physically reach the image to put a screen and capture these images.

Virtual images are formed by the convex and plane mirrors. Concave mirrors can form both real and virtual images depending on the position of the object.

Revision

An image is a reflection of an object in any shiny surface.

There are two types of images, real and virtual images.

The images that are formed in front of the mirror and can be captured on a screen are called real images. Concave mirrors are capable of forming real images.

The images that are formed behind the mirror and cannot be captured on a screen are called virtual images. Convex, concave and plane mirrors are capable of forming virtual images
