D. 90°

Varun’s mom is finding it difficult to cook in the kitchen as there was power cut and she was complaining about it to Varun. He immediately took a plane mirror from his shelf made it stand against a wall such that sun’s rays were focused into the kitchen directly on the cook top, due to the reflection of the mirror. There was some light now and his mother was able to finish her work.

(i) What are the characteristic of the image formed by a plane mirror?

(ii) What values did Varun display?

What is the distance between the image and the plane mirror, if the object is at 15 m?

List four characteristics of the images formed by plane mirrors.

When a plane mirror is rotated through a certain angle, the reflected ray turns through twice as much and the size of the image:

A plane mirror is placed vertically facing due north. An arrow pointing north-east is kept in front of the mirror. In which direction will the arrow point in this image?

Two adjacent walls and the ceiling of a rectangular room are mirror surfaced. The number of images of himself that an observer sees is:

A ray of light is incident on a plane mirror making an angle of 90° with the mirror surface. The angle of reflection for this ray of light will be:

The image of an object formed by a plane mirror is:

The image of an object formed by a plane mirror is:

The figure given alongside shows the image of a clock as seen I a plane mirror. The correct time is:
