Question

12. The diagram below in Fig. 7.17 shows an object XY
in front of a plane mirror MM. Draw on the diagram,
path of two rays from each point X and Y of the object
to show the formation of its image.​

Answer 1

Given:

MM1 is a plane mirror and XY is an object in front of the plane mirror.

To Draw:

The image of the object as formed by the plane mirror.

Steps to Draw :

• Mark the 2 extreme endpoints of the object XY.

• Take a ruler and get the perpendicular distance of each of the extreme in points from the mirror.

• Take the ruler and mark points at same distance on the other side of the liver by extending the lines from the previous step.

• After marking the points using a sharp needle , join the 2 points to get the image .

Concept behind this construction:

• Any plane mirror forms image at a distance equal to the object distance.

• The dimensions of the image is equal to the object dimensions.
