282919 To increase the angular magnification of a simple microscope one should increase

1 the focal length of lens
2 the power of lens
3 the aperture of lens
4 the object size

282920 The focal length of a normal eye lens is about

1 \(1 \mathrm{~mm}\)
2 \(2 \mathrm{~cm}\)
3 \(25 \mathrm{~cm}\)
4 \(1 \mathrm{~m}\)

282921 The minimum magnifying power of a telescope is \(\mathrm{m}\). If the focal length of its eye lens is halved, the magnifying power will become

1 \(\mathrm{m} / 2\)
2 \(2 \mathrm{~m}\)
3 \(3 \mathrm{~m}\)
4 \(4 \mathrm{~m}\)

282922 A person cannot see objects clearly beyond 50 \(\mathrm{cm}\). They power of the lens to correct the vision is

1 \(-5.0 \mathrm{D}\)
2 \(-0.5 \mathrm{D}\)
3 \(+2 \mathrm{D}\)
4 \(-2 \mathrm{D}\)
