The document describes two activities with a plane mirror. In the first activity, a person raises their left and right hands in front of a mirror and observes that their right side appears on the left side of the image and vice versa, demonstrating lateral inversion. The second activity has a person place various objects in front of a mirror at different distances and observe that the size of the image is the same as the object but the distance between the image and mirror is equal to the distance between the object and mirror.

1. Activity 1-
Standing in front of a plane mirror,
raises the left hand. Observes the image
in the mirror.
Repeat the activity with right hand
➔have the food, write with the pen etc. In front of the mirror.
Our right side appears left and
our left side appears right in the image

2. A shift of the lateral side of the images in
the opposite direction is called lateral inversion.

3. The reason for writing
AMBULANCE in that way-
Keep this words in-front of the
mirror and make them read.

4. Activity 2 :-
Place a mirror perpendicular on a table.
Hold different objects like pen, watch, bottle,
marker pen etc. in front of the mirror.
Observe the image.
➢Is the size of the object and the image the same?

5. Keeping a scale in front of the mirror,
place these objects at different positions and observe.
Find out the distance of the image when the distance
of the object from the mirror is increased

6. Note down the difference in
size and distance when move towards the
mirror.

7. The properties of the
image formed by a plane mirror.
➢The size of the image will be the same
as that of the object.
➢The distance between the image and the
mirror is equal to the distance between
the object and the mirror.
➢The image will undergo lateral inversion.
