Question

How does the magnification when the image is at infinity compare with the magnification when the image is at the near point, and which viewing condition is more comfortable?

पर्याय

• The infinity case is one less than the near point case; viewing at infinity is more comfortable

• The infinity case is one more than the near point case; the near point is more comfortable

• The infinity case is one less than the near point case; the near point is more comfortable

• The infinity case equals the near point case; both are equally comfortable

Answer 1

The magnification when the image is at infinity (\[D/f\]) is one less than the magnification when the image is at the near point (\[1 + D/f\]). However, viewing is more comfortable when the image is at infinity, and the difference in magnification is usually small.
