I need help with parts b and d only Nearsightedness and FarsightednessA person with normal vision can focus on objects as close as a few centimeters from theeye up to objects infinitely far away. There exist, however, certain conditions under whichthe range of vision is not so extended. For example, a nearsighted person cannot focus onobjects farther than a certain point (the far point), while a farsighted person cannot focus onobjects closer than a certain point (the near point). Note that even though the presence of anear point is common to everyone, a farsighted person has a near point that is much fartherfrom the eye than the near point of a person with normal vision.Both nearsightedness and farsightedness can be corrected with the use of glasses orcontact lenses. In this case, the eye converges the light coming from the image formed bythe corrective lens rather than from the object itself.▾ Part AWhen glasses (or contact lenses) are used to correct nearsightedness, where should the corrective lens form an image of an object located at infinity in order for the eye to form a clear image of that object?▸ View Available Hint(s)The lens should form the image at the near point.The lens should form the image at the far point.The lens should form the image at a point closer to the eye than the near point.The lens should form the image at a point farther from the eye than the far pointSubmit✓ Correct▾ Part Bfi=Previous AnswereThis effect is achieved by the use of a diverging lens, as shown in the figure.Object atinfinityBSubmitImageIf a nearsighted person has a far point de that is 3.50 m from the eye, what is the focal length f₁ of the contact lenses that the person would need to see an object at infinity clearly?Express your answer in meters.▸ View Available Hint(s)FarpointFor Part foveart do for Part redio foart Bre@or Part 8 keyboard shortcuts for Part 8 help for Part Bm1 of 5Review | Constants> A person with normal vision can focus on objects as close as a few centimeters from theeye up to objects infinitely far away.
