1.	How to solve numericals of mirrors and lenses
Answer» Mirror formula is 1/f aqual to 1/u+1/v The formula for mirrors is 1/f = 1/u + 1/v (f is focal length, u is distance between object and mirror, v is distance between image and mirror). Formula for lens = 1/f =1/v - 1/u. You should fisrt learn the formulas and new sign cartesian for lenses and mirrors Example :-if u r finding magnification use its formula (differ formula\'s for both miror n lenses).Hope helpful! By knowing their formulas
