Question

Magnification is the ratio of ____ of an image

Answer 1

Answer:

Magnification is the ratio of enlargement and reduction of an image

Explanation:

Magnification is the way of enlarging the apparent size of an object. When the magnification of an object is less than 1 it shows reduction in size while when it is greater than 1, it shows enlargement in size. Mathematically, it is given by :

$m=\dfrac{size\ of\ image}{size\ of\ object}$

i.e. $m=\dfrac{enlargement}{reduction}$

Hence, the correct option is (c) " both a and b " i.e. " enlargement and reduction ".
