Answer 1

Answer:

The Focal Length is 1m or 100cm

Explanation:

P=1D

f=?

P=1/f (in "m")     P=100/f(in "cm")

1=1/f                   1=100/f

f=1/1                   f=100/1

f=1m                  f=100cm

The Defect is "Hypermeteropia" Which is also called as "far sightedness". Thus Patient use a "Bi-convex Lens"
