microscopy techniques

Assalamualaikum wbt.

Based on the picture above we all know that I’m going to share to you about microscope. Microscope is used worldwide by human this era.

Lets begin!

This topic lecture is very interesting and I think not everyone knows about the multifunction of each microscope that we have nowadays. learning on this topic makes me realize that even the small living things like bacteria and viruses can be seen and we can observed their internal structure as well. we can even see a 3D structure of the microorganisms under the specific microscope and we can see the exact shape of the microorganisms.. therefore we can know how do they look like and we can observe their motility under the microscope.

there are many types of microscope that I had learnt on this topic. the first one is the common use microscope which is the optical microscope and the electron microscope. 

The types of optical microscope are:

-dark field microscope

-bright field microscope

-fluorescence microscopy

-phase contrast microscopy:

The types of electron microscopy:

-scanning electron microscope:

-transmission electron microscope:

-environmental scanning electron microscope

each type of the microscope give different slide of specimen which is being observed and it helps the scientist to do their researched much better. the uses of microscope is very important to the scientists in order to observed the living things that can't be seen by our naked eyes especially small microorganisms such as bacteria and viruses.

microscope are also varies based on their magnification power where the resolution and refractive index are both important. the shorter the wavelength, the greater the resolution. other than that, under high magnification, the objective lens must be small and need to use oil immersion which has the same RI glass. in order to improve the resolution power.

there are many things that i learnt. what i am hoping from this lecture is that, i hope that I can differentiate and recognize the differences of the images on the specimens under each microscope. i also hope that i will find an alternative way to improve my learning skills on this topic. 

in this week also, we had a brief lecture on prokaryote. before we enter the lecture, Dr Wan assigned us to do some mind mapping  on this prokaryote topic using the applications that she provide to us so that we can understand more in the lecture. this is my mind mapping link that is very simple and good to refresh back what I had learnt.

this is my link for my mind map. have a nice brief to have a look for it. ;)
