B1.1 The world of the microscope Flashcards
equation for magnification
magnification= image/actual
equation for actual
actual= image/magnification
equation for image
image= magnification x actual
if something is 100 times bigger then how many orders of magnification bigger is it
2
what is the magnification that the best light microscopes can get to
x20000
what is the magnification that the best electron microscopes can get to
x2000000
what do electron microscope use to see the specimen
fire beams of electrons rather than light
how do microscopes work
shining light through a specimen on a slide
light is then refracted through an objective lens
and eyepiece lens forms a magnified image in your eye
when was the first light microscope invented
in the 1700s
when was the first electron microscope invented
in the 1930s
