Question

a convex lens of focal length is 10 centimetre calculate its power​

Answer 1

Answer:

power of lens =100/f

Explanation:

given that

f=10

so 100/10

=10

there fore power is 10

Answer 2

hlo mate ✌️

Given :

focal length = 10 cm

1m = 100cm

focal length = 0.1 m

Power = 1 /focal length

• Power = 1/0.1
• power = 1×10

Power = 10 Dioptre

Hope it helps ❣️
