Question

Write the spherical mirror's formula and explain the meaning of each symbol used in it.

Answer 1

This equation predicts the formation and position of both real and virtual images in thin spherical lenses$.$ It is valid only for paraxial rays$,$ rays close to the optic axis$,$ and does not apply to thick lenses$.$ Also$,$ it can be determined the curvature ratio of the lens$.$

$\frac{1}{\left(objectdistnce\right)}+\frac{1}{\left(imagedistance\right)}=\frac{1}{\left(focallength\right)}$

focal length$=$ curvature/2

the equations are$:$

$\frac{1}{0}+\frac{1}{1}=\frac{1}{f}$

$F=\frac{r}{2}$

where$:-$

$O:-$ object distance

$I:-$ formed image distance

$f:-$ focal length

$r:-$ curvature radius$.$
