The microscope in cell studies — practice question

A specimen of plant tissue is initially examined with a microscope by means of red light of wavelength $650\,\text{nm}$. The same specimen is then viewed again under identical conditions, except that green light of wavelength $510\,\text{nm}$ is used. What change occurs to the magnification and the resolution when green light is used instead of red light?

  • Amagnification decreases, resolution decreases
  • Bmagnification increases, resolution increases
  • Cmagnification remains the same, resolution decreases
  • Dmagnification remains the same, resolution increases
