Question

The resolving power of a compound light microscope will be maximum if the source of light is

• A. Red.
• B. Yellow.
• C. Green.
• D. Blue.

Answer 1

The correct option is D Blue.

• A compound light microscope is a microscope with more than one lens and its own light source. In this type of microscope, there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen.
• Compound Microscopes are also known as High Power or Biological microscopes. They are used to view specimens NOT visible to the naked eye such as blood cells.
• Objective Lens: Compound Microscopes typically, include 3-5 objective lenses that range from 4x-100x.
• The resolving power is the capacity of an instrument to resolve two points which are close together.
• The resolving power of a compound microscope is 0.25μm and the resolving of a compound light microscope will be maximum if the source of light is blue.

So, the correct option is D.
