it is also difficult to see anything as small as DNA or viruses

Question 3

electron microscope

Answer 3

uses beams of electrons that are focused by magnetic fields.

they offer higher resolution, ability to see viruses, and can see much smaller cellular structures

electron microscopes can only be used on dead specimens though

Question 4

refraction

Answer 4

the fact or phenomenon of light, radio waves, etc., being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density.
change in direction of propagation of any wave as a result of its traveling at different speeds at different points along the wave front.
measurement of the focusing characteristics of an eye or eyes.
