Question

Does the magnifying power of a microscope depend on the colour of the light used? Justify your answer.

Answer 1

Yes, the magnifying power of a microscope depends on the colour of the light used.

The physical parameters which determine the resolution include the wavelength of light, and the light-gathering power of the objective and condenser lenses.

The ability of the human eye to see details may be compromised to some extent if there is blue or violet light. Green light is most suitable for the human eye. So the makers of microscopes correct their simplest lenses (achromats) for green light.
