Question

M=-2 the imagine equals what?

Answer 1

Answer:

Image is twice as large as the object, and inverted

Explanation:

When an object is placed in front of a mirror, the mirror produces an image.

The magnification of the image is a number telling how much the size of the image is enlarged/diminished with respect to the object.

It is given by

$M=\frac{y'}{y}$

where

M is the magnification

y' is the size of the image

y is the size of the object

In this problem,

M = -2

This means that:

$y'=My\\y' = -2y$

So, we can conclude the following:

- The size of the image is twice the size of the real object

- The image is also inverted, because of the presence of the negative sign in the equation
