CBSE Class 10 Answered

Dear student

Pls check at ur end there cud be an error in the units of qunatity of 0.5 cm..it cud have been 0.5 m.

In such case:

The eye is suffering from myopia.

For correction,

image requires to be formed at v= -0.5m

object at infinity (for objects like stars), u = - (infinity)

Uisng lens formula

1/f = 1/v -1/tituting for the value, f = - 0.5 m

Substituting for the value

f = - 0.5 m

Power of the corrective lens required

P = 1/f =- 1/0.5= -2D
