Question

If M is the magnification of a mirror, match the following values to the orientation and height of image.

• A. Erect image
• B. Inverted image
• C. Same size as object

Answer 1

The magnification of a mirror can be calculated as $M=\frac{h_i}{h_o}$
where $h_i$ is the height of the image and $h_o$ is the height of the object.

When the value of magnification is equal to 1, it implies that the height of the object is equal to the height of the image.

When the value of magnification is negative value we get an inverted image.

When the value of magnification is a positive value we get an erect image.
