microscopy

    Cards (6)

    • microscopes let us see things that we cannot see with the naked eye
    • light microscopes use light and lenses to form an image of a specimen and magnify it. they let us see individual cells and large subcellular structures.
    • electron microscopes use electrons to form an image. they have a much higher magnification and resolution than light microscopes.
    • resolution is the ability to distinguish between two points, so a higher resolution gives a sharper image.
    • electron microscopes let us see much smaller things in more detail.
    • magnification = image size / real size
