Question

Can someone write me an essay on microscope ​

Answer 1

Hello! :)

I would if I could but you should use your own words and knowledge to write your essay—no one can do it for you. That’s how you learn and that’s how life is. But to help you out, here are tips and basics for writing your essay:

• Introduction: This is the first part of your essay, and which to a great extent; define how you will unravel the structure. The question is what role does it play in a piece of literary composition? Well, depending on how you begin, introductions are flexible and often, writers craft them in own style. Whether you want to define a concept, start with a saying, present an analogy or pose a question, a five-paragraph essay will, and must always have an introduction.

• Body paragraphs: Refer to the main sections of a linear essay. It is here where a writer argues out his or her points. However, the style with which this should be done may vary from one essay type to another. In fact, even if you were to seek help from the best essay writing websites, the only way you can be sure of scoring high marks is ensuring that at least three main paragraphs are making up the body text.Each section answers the main question or thesis statement coming at the foremost parts and with supporting evidence/details; an essayist should be able to demonstrate how this contributes to the overall essay writing structure.

• Conclusion marks the end of a five-paragraph write-up. Having introduced a point from the start, it is important to let readers know that it is that time a writer brought everything to an end with a final full stop coming hot on the heels of such a resolution. There are many ways of concluding an essay. Whether you want to seize the opportunity and summarize every aspect of the story using a saying or simply recall the main thematic/thesis statement, it is imperative to note that a good story does not stop, but rather, it ends, and readers should be aware of it.

Hope I answered in time.

Good luck and get starting!

1. Introduction

A microscope is an instrument used to investigate tiny objects which cannot be seen by naked eyes. There exist three types of microscopes which are optical microscopes, electron microscopes, and scanning probe microscopes. (1) Six types of microscopes talked in this report are reflected and transmitted light microscope, scanning electron microscopes (SEM), transmission electron microscopes (TEM), focused ion beam (FIB), and atomic force microscope (AFM).

1.1 Reflected light microscopes

Reflected light microscope is a type of microscope using visible light and a system of lenses to magnify images of small samples. It is used to examine opaque specimens which will not transmit light and other materials such as ceramics.The reflected light travels through the objective lens, which in this arrangement acts as both a condenser and an objective, and strikes the specimen.It is then reflected off the specimen back up through the objective lens, the head, the eyepieces, and finally to the eye.(2)

1.2 Transmitted light microscope

Transmitted light microscope is a type of microscope where the light transmits from a source on the opposite side of the specimen from the objective. Usually the light is passed through a condenser to focus it on the specimen to get very high illumination. (3)After the light passes through the specimen, the image of the specimen goes through the objective lens and to the oculars where the enlarged image is viewed.

1.3 Scanning electron microscope

The scanning electron microscope (SEM) is one kind of electron microscope. The SEM utilizes a very fine probing beam of electrons scanning over the specimen to emit a variety of radiations. The signal which is proportional to the amount of radiation leaves an individual point of the sample at any time. The signal obtained from one point will display the information of that point. In practice, the points follow one another with very high speed so that the image of each point becomes an image of a line, and the line move down the screen so rapidly that the naked eye sees a complete image on the computer. SEMs are patterned after reflecting light microscopes and will yield similar information

1.4 Transmission electron microscope

A transmission electron microscope (TEM) works much like a slide projector. A projector shines a beam of light through the slide, as the light passes through it is affected by the structures and objects on the slide. These effects result in only certain parts of the light beam being transmitted through certain parts of the slide. This transmitted beam is then projected onto the viewing screen, forming an enlarged image of the slide. TEMs work the same way except that they shine a beam of electrons through the specimen. Whatever part is transmitted is projected onto a screen for the user to see. TEMs are patterned after transmission light microscopes and will yield similar information.

1.5 Focused ion beam

A focused ion beam system (FIB) is a relatively new tool that has a high degree of analogy with a focused electron beam system such as a scanning electron microscope or a transmission electron microscope. In SEM and TEM the electron beam is directed towards the sample generating signals that are used to create high magnification images of the sample. The major difference with a focused ion beam system is the use of a different particle to create the primary beam that interacts with the sample. A highly focused ion beam is used instead of electrons in FIB. As the beam scans the surface of the sample, a highly magnified image is created, which allows the system operator to view the samples microscopic features clearly.
