B) -1.5 D
C) +2.5D
D) +0.5D
Correct Answer: C
Solution :
Hypermetropia can be removed by using a convex lens Focal length of used lens \[f=+d=+40\text{ }cm\]= + (defected near point) \[\therefore \] Power of lens \[=\frac{100}{f(cm)}=\frac{100}{40}\]\[=2.5D\]You need to login to perform this action.
