Answer 1

Hi

Here is your answer,

Concave lens or it can be diverging lens it is used to correct the vision of a myopic person.

So already they have mentioned in the question that distance beyond it's object is 1.2m

Now for viewing the distant object so concave length of focal -1.2m should be used.

Now, f=-x = -1.2 m

Now, Power of lens = 1/f = 1/(-1.2)m

= -0.83m


Hope it helps you !

Answer 2

The corrective lens that should be used to restore proper vision is concave lens of suitable power.

HOPE IT HELPS

Thanking you
