NIOS Class 10 Science Activity 15.2 Light Energy

In this activity, we will learn lateral inversion and the general characteristics of images formed in a plane mirror. In the previous activity 15.1, we have already discussed reflection by a plane mirror.

 

Light Energy Activity

This activity is based on the NIOS Class 10 science and technology (212) Chapter 15- Light Energy, Module 4.

Lateral Inversion in Image Formed by a Plane Mirror

Aim

To study lateral inversion

Materials Required

   1.  Plane mirror

   2. Paper or notebook

Procedure

We place a plane mirror in a vertical position on a table. We have a notebook or paper on which Letters and symbols - #, O, dke, P, OH are already written.

We place this notebook or paper in front of the plane mirror and observe the images formed.

Observation

We can easily observe the images formed in the plane mirror.

Explanation

The images of some objects, like O, H,#, look the same as the object because they are symmetrical.

But objects like P, dk,e, and OH appear reversed. The left side of the object appears as the right side in the image, and vice versa, which is called lateral inversion.

Conclusion

This activity explains that the plane mirror forms an erect, virtual image of the same size, and it also shows lateral inversion of asymmetric objects.

Frequently Asked Questions

   1. What is lateral inversion?

Answer – Due to reflection in a plane mirror, the left side of the object appears right side of the image and vice versa, this is called lateral inversion.

   2. Do all objects show lateral inversion in a plane mirror?

Answer – No, only asymmetric objects show lateral inversion.

   3. What type of image does a plane mirror form?

Answer – A plane mirror forms an erect, virtual, laterally inverted, and the same size image.
