Question

a person with myopia eye is not able to see objects beyond 2m from it determine the nature the focal length and the power of lens used to correct the defect
Answer it fast ⏩​

Answer 1

Explanation:

U= infinity

v= 2m

1/f=1/2-1/v

1/f=-1/2-1/infinity

1/f= -1/2

F=2m

P= 1/f

P=1/-2

P=0.50

FOCAL LENGTH= -2M

POWER LENS = -0. 5 DIOPTRES

Answer 2

Answer:

That means, radius of curvature decreases and focal length decreases. For a clear vision, the image must be on the retina. The image distance is therefore fixed for clear vision and it equals the distance of retina from eye lens. It is about 2.
