A Magnification Question

Post by Azedenkae » Wed Aug 29, 2007 5:27 am

Ok, let say I have to draw the shape of something under a microscope, and after drawing it, the second question is 'State the magnification of your drawing and show how you calculated it.'

Would the magnification be MA = Mo x Me (magnification of eyepiece x magnification of object) or MA = Observed Length/Actual Length?

Can anyone help me with which should be the right way? Because this was a question for one of the praticals and half of the class did one way, half of the other did the other way, and the teacher is blur. ><''

MoXMe is usually what you use, rarely do you have the actual length of whatever it is you're viewing.

MoXMeis the answer.

K thanks, just what I thought. So the teacher is indeed wrong (he's good at everything except for anything to do with the microscope >.>'')

Well, about 90% of biology has to do with the microscope :D

Where did you get that idea?

I am working in microbiology and I don't even remember the last time I used a microscope... Probably during my second year in university back in the first half of the nineties...

true. But microbiology still makes use of microscopes. I was thinking at a more theoretical level.

I did not say (micro)biology do not use microscopes anymore. In fact I will soon start a new project that will hopefully includes some fancy microscopic techniques, but i wanted to point out that most of the biology now do not make use of microscopes, because you do not really need to see things any more, you mostly record effects etc... So the microscope is not the ubiquitous ever important it used to be.
