Answer:
10 cm or 0.1 m
Step-by-step explanation:
Power ( in diopters ) = 1 / Focal Length ( in meters )
⇒ 10 D = 1 / Focal Length
⇒ Focal Length = 1 / 10 D
⇒ Focal Length = 0.1 m = 10 cm
Hence Focal Length is 10 cm.

Power = 10 D
focal length = f
We know that
P = 1/f
=> 10 = 1/f
=> f = 0.1m
=> f = 10cm
Thus focal length is 10cm. Since focal length is positive, it is a convex lens.
