The Difference Between Light And Electron Microscopes?

• What are the two main types of microscopes discussed in the video?

  Light microscopes and electron microscopes
• Why are light microscopes considered conventional microscopes?


  Because they are commonly used in classrooms
• What are the advantages of light microscopes?


  They are small, easy to use, and relatively cheap
• What is the resolution limit of light microscopes?


  0.2 micrometers
• What does a resolution of 0.2 micrometers imply about the details that can be seen?


  Details less than 0.2 micrometers apart will appear blurry
• What type of structures can light microscopes not adequately study?


  Sub-cellular structures like mitochondria
• What are the characteristics of electron microscopes?


  They are big, expensive, and hard to use
• What is the benefit of using electrons in electron microscopes?


  Electrons have a wavelength of just 0.1 nanometers
• What is the maximum resolution of electron microscopes?


  0.1 nanometers
• How does the resolution of electron microscopes compare to that of light microscopes?


  Electron microscopes have 2000 times better resolution
• Why is a smaller resolution value considered better?


  It allows for seeing tinier details
• What type of images can electron microscopes produce without going blurry?


  Images with much higher magnifications
• What sub-cellular structure is mentioned as being studied with electron microscopes?


  Mitochondria
• What can be seen clearly in the image taken with an electron microscope of a pancreatic cell?


  The nucleus and some 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), not suitable for sub-cellular structures

  
  

  **Electron Microscopes:**

  • Pros: High resolution (0.1 nanometers), can study sub-cellular structures
  • Cons: Large, expensive, hard to use
• What should you remember about the main differences between light and electron microscopes?
