Question

a person with myopic eyes is not able to see objects beyond 3 determine the nature focal length and power of the corrective lens​

Answer 1

lens may be real and magnified. power of the lens =3/-d

Answer 2

Answer:

Explanation:

given ,v = -3m or -300cm

u = -infinity

f = ?

according to lens formula ,

1/f = 1/v - 1/u

1/f = -1/300 - (-1/infinity)

1/f = -1/300 + 1/infinity

focal length = -300 cm or -3metre

now,

power = 1/focal length(metre)

power = -1/3

power = -0.33 dioptre

nature = myopia ( short sightedness)
