Question

6)The power of a convex lens of focal length 10cm is

-1 D
+1 D
-10 D
+10 D ​

Answer 1

Answer:

The power of a convex lens of focal length 10cm is +10D

Answer 2

Answer:

power of convex lens(D) = 1/f

10cm = 1m

D = 1/1

D = +1 D

Explaintion — The power always measured to convert focal length in meters
