Question

what do you mean by magnification is -3​

Answer 1

Explanation:

$\huge\green{\mid{\fbox{{คภรฬєг⤵}}\mid}}$

Magnification is the process of enlarging the apparent size, not physical size, of something. When this number is less than one, it refers to a reduction in size, sometimes called minification or de-magnification.

$\huge\fbox\red{hσpє}\huge\fbox\pink{ít}\fbox\green{hєlp}\huge\fbox\blue{yóû}$

$\huge\fbox{\red{\underline{mαrk \; mє \; вrαínlíєѕt \; plєαѕє ♥}}}$

$\large\bf{\underline\blue{❥thαnk \; чσu ♥♥}}$
