How can you tell what kind of bacteria it is through a lightmicroscope just by looking at it...? By looking at their form?
Do they distinct in any way? :(

I only know how to see the different between eucaryotes and procaryotes...

By their shape you could distinguish which type they are...

On the title you ask about how to differ between bacteria and archaea..well, for the experiment, you have to work with series of chemical agent and stains..but I can say that the difference is in their cell wall.
Bacteria
divides into 2 major groups, gram+ and gram- bacteria. gram+ cell wall consists of monolayered wall, thickness about 80 nm in periplasm and the outer wall formed from the bonds of N-acetylmuramic acid and mesodiaminopimelic acid which give the rigid structure of the wall. Gram- bacteria's cell wall consists of multilayered wall but the periplasm is only 2 nm thick..

Archaeon
Archaeon doesn't have cell wall, it only contains cell membrane which is formed by monolayered lipid tetraether or bilayer one..the unit structure of the cell membrane consists of glycerol and phyntanyl through an ether bond linkage...(in bacteria and eukarya it's ester bond linkage).
