1. Microscope Types and Purposes

Key Concepts & Definitions

  • Microscope : A scientific instrument used to make very small objects appear much larger so that cells, microorganisms and tiny structures can be studied.

Essential Points

📌 A compound light microscope uses multiple lenses and allowed scientists such as Robert Hooke to see cells, whereas an electron microscope uses electrons and provides much greater magnification for viruses and tiny cell structures.

Memory Hook

Light microscopes use light, whereas electron microscopes use electrons.

2. Microscope Parts and Use

Essential Points

  • The main parts of a light microscope are:
    • the eyepiece lens
    • the objective lens
    • the stage
    • the coarse focus knob
    • the fine focus knob
    • the arm
    • the base
    • the light source
    • the stage clips
