What is the focal length of a lens whose radius of curvature is 30 cm.?? |
|
Answer» Radius of curvature,r=30cmFocal lenght, f =?Now, f=R/2 f= 30/2 Therefore, f=15 cm \xa0Radius of curvature R = 30 cmRadius of curvature = 2\xa0×\xa0Focal length (f)R = 2 fHence, the focal length of the given convex mirror is 15\xa0cm. |
