Okay, this question here says, from figure 6 .2, what microscope or microscopes should you use to see the smallest bacteria? so, the smallest bacteria according to the figure is for, well, their size is going to be 100 nanometers.
00:24
Okay, so in this case, these bacteria here are too small to be observed using a standard line microscope due to the limitations of optical resolution.
00:36
So, a line microscope, remember, has a resolution limit of approximately 200 nanometers, which means that they cannot distinguish objects that are closer together than this distance.
00:45
So, to observe bacteria at the nanometer scale, such as 100 nanometers, we should use an electron microscope.
01:05
Okay, and two common types of electron microscopes that can achieve the necessary resolution are transmission electron microscope and also scanning electron microscope.

So, these two microscopes can see the smallest bacteria...
