Electron Microscope

Question 1

In reference to electrons what happens to heat ?

Answer 1

heat →electrons leave orbit and act like radiation.
the negative charge allows them to be focused (works in vacuum).

Question 2

In electron microscope what kind of energy is there ?

Answer 2

short ⋋ great energy.

Question 3

What is (what about the transmission of an electron microscope) ?

Answer 3

-uses beams of electrons through specimen.
-magnification of 2 000 000×
-has two limitations :
*good for only thin specimen.
*only dead cells can be observed.

Question 4

What is (what about the scanning of an electron microscope) ?

Answer 4

-electrons are reflected from surface of specimen.
-produces a 3D image.
-good for thicker specimens.
-lacks the magnification and resolution of the transmission electron microscope.
