- Microscopy
- Microscopes
- Let Us See Things We Can't See With A Naked Eye
- Microscopy Techniques Have Developed Over The Years
- Due To The Development Of Tehcnology And Knowledge
- Light Microscopes
- Use Light And Lenses To Form Image Of Specimen And Magnify It
- Makes It Look Bigger
- Let Us See Individual Cells and Large Subcellular Structures
- Examples: Nuclei
- Use Light And Lenses To Form Image Of Specimen And Magnify It
- Electron Microscopes
- Use Electrons Instead Of Light To Form Image
- Have A Much Higher Magnification Than Light Microscopes
- Have A Higher Resolution
- The Ability To Distinguish Between 2 Points
- A Higher Resolution Gives A Sharper Image
- Let Us See Smaller Things In Detail
- Example: Mitochondria Chloroplasts
- Let Us See Tinier Things Like: Ribosomes Plasmids
- Formula For Magnification
- You Can Calculate The Magnification By Using A Formula
- Magnification= Image Size ÷ Real Size
- The Image Size And Real Size Should Have The Same Units
- To Work Out The Image Size Or Real Size You Can Rearrange The Equation
- Image Size ÷ Magnification x Real Size
- Real Size ÷ Magnification x Image Size
- Rearrange The Formula
- Fill In Values Known
- Remember Units In Answer
- Convert Units
- Microscopes
