Hello everyone, in this question we have been said to list the metric unit of measurement that are used for microorganisms.
00:09
So the microorganisms are measured in micrometer like 10 -6 meter which is 6 times smaller than a meter and also measured in 10 -9 meter.
00:26
So these units are used to measure the thickness and size of the microorganism as well as the colloidal particles.
00:35
Then we have been asked to diagram the path of light through a compound microscope.
00:41
So here we have the eye, then we will look through the eyepiece.
00:49
So here it is, here is the source of light and there is a condenser lens that is present here and there is the stage on which the specimen is kept here and there is a objective lens.
01:15
So basically here the light will pass from the condenser lens.
01:21
So the condenser basically condenses the light to the specimen and now it will illuminate the specimen and then here it will travel.
01:32
Then from the objective lens it will again condense and then through the projector lens it will diverge and then we will get the image here like.
01:44
So this is how the compound light microscope works.
01:48
Then we have been asked to define total magnification and resolution.
01:54
So the total magnification is the product of objective lens and ocular lens.
02:06
The total magnification for example we can take the power of objective lens as 4x, 10x, which is then multiplied with the eyepiece that is 10x.
02:20
So here the total magnification will be 400x.
02:26
Then the resolution is the ability of the microscope to distinguish between two closely placed object that is at the minimum, that is the minimum distance at which the two distinct point of specimen can be seen properly in a separate manner.
02:48
Then we have been asked that identify the use for dark field phase contrast and differential interference contrast, fluorescence confocal, two -photon, scanning acoustic microscope and compare each with bright field illumination...
