Play with a mirror
Write your name with a sketch pen on a thin sheet of paper, polythene or glass. Read your name on the sheet while standing in front of a plane mirror. Now look at your image in the mirror.
उत्तर
Activity:
- Write your name with a sketch pen on a thin sheet of paper, polythene, or glass.
- Stand in front of a plane mirror and read your name on the sheet.
Observation:
- When you look directly at the sheet, your name appears normal.
- When you look at the image in the mirror, your name appears reversed (laterally inverted).
Explanation:
- A plane mirror creates an image that is a mirror reflection of the object.
- This results in lateral inversion, where the left side of the object appears on the right side in the image and vice versa.
Conclusion:
By performing this activity, you can observe how a plane mirror reverses images, demonstrating the concept of lateral inversion.
