Erect vs Inverted Images

Ramesh was going to the market by car with his father.

When he looked into the side mirror.

He found that the image in the side mirror was exactly the same as the car behind him.

When he returned home and sat down to dinner, he saw his face in a shiny spoon.

He observed that his face was looked the same on the bulge side of the spoon.

But, the image of the face was up-side-down in the curved side of the spoon.

Now, he tried to compare all the three images that he was observed.

And he found that two were the same but, one was different.

He was too curious to know the reason behind that.

So now, we will help him to know the reason behind it.

Let's discuss the difference between erect and inverted images.

Images are formed by the reflection of light from highly shiny surfaces.

Some images are the same as the object and some images are having up-side-down.

Images, which are the same as the original object are called erect images such as the image in the side mirror of a vehicle.

The image formed by plane mirror is another example of an erect image.

Image, whose up-side down is called inverted image such as the image in the concave side of a shiny spoon.

The image formed by a pinhole camera is another example of an inverted image.

Erect images are formed in a plane mirror.

When two rays virtually intersect each other at a certain point and direction is the same as the object.

An inverted image is formed by spherical mirrors when two rays actually intersect each other.

These are the difference between erect and inverted images.

Revision

Usually, two types of images of an object can be seen in daily life.

Erect images are those images which are same as the original object.

Erect images are formed by the plane mirror.

Inverted images are those whose up-side-down.

An inverted image is formed by spherical mirrors when two rays actually intersect each other.
