Question

If the magnification of a body of size 1 m is 4, what is the size of the image ?

Answer 1

Answer:

The size of an image = 4 m.

Explanation:

As per the question,

Given data are:

Size of the object = 1 m

Magnification of a body = 4

As we know that magnification is the ratio of the size of an image to the size of an object, mathematically it is represented as:

$m = \frac{size \ of \ an \ image}{size \ of \ an \ object}$

∴ $4=\frac{size \ of \ an \ image}{1}$

or,

size of an image = 4

Hence, the size of an image = 4 m.
