1/v + 1/u = 1/f​

Answer 1

Answer

$\huge \sf\blue{\colorbox{pink}{Answer☘}}$

The formula is a relation between the object distance u , inmage distance v and the focal length from the pole of the concave mirror. ... Let P be the pole of the concave mirror. Let P, F , C be the pole, focucal point , and centre of curvature along principal axis . So, PC = 2PF , as r = 2f
