Question

write the formulas associated with spherical mirror so far along with the meaning of each symbols​

Answer 1

Answer:

1/v + 1/u =1/f

This is mirror formula.

v= image distance

u= object distance

f= focal length

m= v/u= h'/h

m= magnification

h'= height of image

h= height of object

Answer 2

$\huge \fbox \blue{Answer:}$

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.

$\frac{1}{(object \: distance)} + \frac{1}{(image \: distance)} = \frac{1}{(focal \: lenght)}$

focal length= curvature/2

focal length= curvature/2the equations are:

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

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