Microscopes

• What does microscopy refer to?

  The use of microscopes
• What are the main components of a light microscope?

  Base, arm, light source, stage, lenses
• What supports the entire light microscope?

  The base at the bottom
• What connects the bottom to the top of a light microscope?

  The arm
• What type of light source can be used in a light microscope?

  A lamp or a mirror
• Where do we place the microscope slide?

  On the stage
• How many objective lenses are typically found in a light microscope?

  Three objective lenses
• What are the possible magnifications of the objective lenses?

  10x, 20x, and 50x
• What is the function of the eyepiece lens?

  To look into the microscope
• What are the coarse and fine focusing knobs used for?

  To help focus the image
• What does the term 'object' refer to in microscopy?

  The real object or sample being viewed
• What does the term 'image' refer to in microscopy?

  The visual representation seen through the microscope
• How does light travel through a light microscope?

  It reflects off the mirror and through the object
• 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
• How can two images of onion cells have the same magnification but different resolutions?

  One image may be blurrier than the other
• What should you check for practice questions related to microscopy?

  The link in the video description
• What happens to the image when the resolution is lower?

  The image appears blurrier with less detail
