Microscopy

• what is magnification?


  How many times larger the image is than the object
• what is the equation for magnification?


  image size ÷ object size
• what is an image?


  what we see when we look down the microscope
• what is an object?


  real object or sample that you are looking at
• what is resolution?


  shortest distance between two points on an object, that can still be distinguished as two separate entities

  (a measure of how detailed the image is)
• what is the equation for image size?


  object size x magnification
• what is the equation for object size?


  imagine size ÷ magnification
• what is the equation for total magnification?


  Eyepiece magnification x Objective lens magnification
• how do light microscopes work?

  use light and lenses to form an image of a specimen and magnify it
• what are the two types of microscopes?

  light and electron
• what do electron microscopes used instead of light?

  electrons
• what do electron microscopes give us the ability to see?

  smaller objects in more detail, like the internal structure of mitochondria and chloroplasts. even tinier things such as ribosomes and plasmids
