Give the relationship of magnification with focal length of a spherical mirror

Dear Student ,

If u =object distance   v= image distance   f= focal distancethen 1v+1u=1f is teh general equation for  a spherical mirror irrespective of signso 1+vu=vfnow magnification  m= -vuso          1-m=vf          f=v1-m [ans]
Regards

m= -v/u  and 1/v +1/u=1/f

Here is the ans...
f=v/(1-m)
Hope it will help you... :-)
