Question

Magnification produced by a rear view mirror fitted in vehicles
(a) is less than one
(b) is more than one
(c) is equal to one
(d) can be more than or less than one depending upon the position of the object in front of it.​

Answer 1

Answer:

(a) is less than one

Explanation:

We know, magnification(M)=

$\frac{height \: of \: image}{height \: of \: object}$

If the magnification will be 1 or more than 1, then the height of image will be equal or greater than the height of object. So, only a part of the image will be viewed through the possible aperture of the mirror. This situation will not provide the driver with the detailed idea of motion of vehicles following.

Hence, Magnification produced by a rear view mirror fitted in vehicles is less than one.
