Microscopes- basics

Magnification: How many times larger the image is than the actual object 

Resolution: Ability to see two objects as seperate objects 

Optical microscopes

  • ADVANTAGES:
    • cheap, easy to use, portable, can study whole living specimens 
  • DISADVANTAGES 
    • Small magnification ability 
  • Photomicrograph: image seen in a light microscope
  • Light have wavlength of 400 to 700nm so objects closer together than 200nm re seen as one object 

Calculating magnification 

  • IAM- Image/ magnification x actual
