Given,
Distance of far point x = 2 m
Focal length of the corrective lens to view distant objects correctly f = -x
= -2 m Ans.
Power of the lens P = 1/f
= 1/(-2)
= -0.5 D Ans.
Distance of far point x = 2 m
Focal length of the corrective lens to view distant objects correctly f = -x
= -2 m Ans.
Power of the lens P = 1/f
= 1/(-2)
= -0.5 D Ans.
