Question

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?

Answer 1

(i) Image formed by plane mirror is of the same size as of the object. Positive value of magnification indicates that image formed by plane mirror is erect. Image formed by plane mirror is at same distance as the object but behind the mirror. Magnification of image is +1.

 The image is virtual. 

(ii) Varun made an arrangement for the light so that his mother could finish the work easily this shows that Varun is caring and responsible towards his mother. Also, he has used his knowledge of plane mirrors to get the light this shows that he is also quite clever and intelligent also he is the serious student who focuses on the practical aspect of things taught in class and applies them in a day to day use. 

In other words, Varun had put the science to the real use.
