Question

What type of image is formed by a lens if m = -1.6?

Answer 1

Answer: the image is larger than the object and is real.

Explanation:

Answer 2

The image formed from the lens is real, inverted and enlarged

Explanation:

The magnification of a lens is given by:

$m=\frac{y'}{y}=-\frac{q}{p}$ (1)

where:

y' is the size of the image

y is the size of the object

q is the distance of the image from the lens

p is the distance of the object from the lens

For this lens, the magnification is

m = -1.6

We notice the following:

- The magnification is negative

- The magnification is larger than 1

Looking at eq.(1), we can therefore make the following conclusions:

- SInce $m=\frac{y'}{y}$ and $|m|>1$, it follows that $|y'|>|y|$, so the image is larger than the object

- Since $m=\frac{y'}{y}$ and $m$, it follows that $y'$ (since y > 0 for convention): this means that the image is inverted

- Since $m=-\frac{q}{p}$ and $m$, it follows that $q>0$ (since p > 0 for convention): this means that the image is real
