  • What are the main components of a light microscope?
    Base, arm, light source, stage, lenses
  • What is the function of the light source in a microscope?
    To illuminate the object being viewed
  • What is the stage of a microscope used for?
    To hold the microscope slide
  • What is magnification in microscopy?
    How many times larger the image is than the object
  • What is the equation for magnification?
    Magnification = image size / object size
  • What is resolution in microscopy?
    The shortest distance between distinguishable points
  • How does resolution affect the image quality?
    Higher resolution means more detail and less blur
  • What are the key terms related to microscopy?
    • Object: Real sample being observed
    • Image: Visual representation seen through the microscope
    • Magnification: Size of image compared to object
    • Resolution: Shortest distance between distinguishable points
  • What is the relationship between magnification and resolution?
    • Magnification increases size of image
    • Resolution determines clarity and detail
    • Higher magnification does not guarantee higher resolution
  • How does light travel through a light microscope?
    It reflects off the mirror, through the object, and lenses
  • How does resolution affect the clarity of an image?
    Higher resolution means more detail and less blur
  • What happens to the image if the resolution is low?
    The image appears blurry with less detail
  • Why are light microscopes considered conventional microscopes?
    They are commonly used in classrooms
  • What is a key advantage of light microscopes?
    They are small, easy to use, and cheap
  • What types of structures can light microscopes not effectively study?
    Sub-cellular structures like mitochondria
  • What are the characteristics of electron microscopes?
    They are big, expensive, and hard to use
  • What type of structures can electron microscopes study effectively?
    Sub-cellular structures like mitochondria
  • What are the pros and cons of light and electron microscopes?
    Light Microscopes:
    • Pros: Small, easy to use, cheap
    • Cons: Limited resolution (0.2 micrometers)

    Electron Microscopes:
    • Pros: High resolution (0.1 nanometers)
    • Cons: Large, expensive, hard to use
