According to formula

p = 1/f

2 = 1/f

hence f=1/2 => f=0.5 ans

p = 1/f

2 = 1/f

hence f=1/2 => f=0.5 ans

The Brainliest Answer!

P=1/f

P=2.0D

By substituting value of P in the formula

2.0=100/f.… ( when f is in cm)

f=100/2

f=50cm

Hence the focal length of the lens whose power is 2.0D is 50cm or 0.5m.
