Question

The magnification produced by a mirror is - 1.5. What does it signify about the image formed ?

Answer 1

Magnification is the ratio of image size to object size.

$M=\pm \frac{h^{\prime }}{h}$ ($\pm$ according to sign convention)

When the magnification is $-1.5$, it implies that image size is $1.5$ times than the actual object size but is inverted.
