then select the lowest ocular power (4x) to set microscope into low power. The reposition slide into the circle of light by turning the two knobs located at the right of the microscope. The top knob moves slide back and forth‚ where as‚ the bottom knob positions the slide from side to side. Then adjust the focus using the coarse focus and fine focus knob‚ using the coarse focus first causing a move rapid movement. ALWAYS make sure the microscope is in its lowest power when using the coarse

Introduction: The light microscope helps see the microscopic world that the naked eye cannot see. If there were no microscopes in the world‚ than it would be very difficult to understand the many particles that surround the living world. The purpose of this lab experiment is to become familiar with a microscope. It is hypothesized that it will be difficult to use the microscope without any previous training and that the parts and their function must be learned in order to

Introduction Microscopes have brought to light a new realm of information that originally laid dormant and invisible to the naked eye. It has enhanced biology and brought forth great advancements into the study of living organisms. Many discoveries have been achieved through the microscope. One of the major ones is the cell theory that we have talked about in this chapter. Having a microscope enables us to study even the smallest of details in organisms and allows us to conduct research. Another

Microscopes and Microscopy Introduction The purpose for including a lab on microscopy in his course is because it is a very important tool in making detailed observations. This lab helps the average person realize that there is much more to things than what you see with the naked eye. In the field of human biology microscopes are very important for many reasons. In the late 1500’s a scientist named Zacharias Janssen created the first microscope of it kind and now we have several microscopes

Compound Microscope Parts A high power or compound microscope achieves higher levels of magnification than a stereo or low power microscope. It is used to view smaller specimens such as cell structures which cannot be seen at lower levels of magnification. Essentially‚ a compound microscope consists of structural and optical components. However‚ within these two basic systems‚ there are some essential components that every microscopist should know and understand. These key microscope parts are illustrated

Agasthya who gave me such a wonderful topic and whose encouragement‚ guidance and support from the initial to the final level enabled me to develop an understanding
Premium Microscope Electron microscope Scanning electron microscope
The electron microscope‚ instrument that produced the first magnified image showing three-dimensional’ and highly magnified image of a small object. It directs a beam of electrons rather than light through a specimen. The beam of electrons is created from an electron gun. This beam then travels through the length of the microscope cylinder‚ which contains the lenses‚ the specimen chamber‚ and the image-recording system. Two types of electron lenses are used‚ electrostatic and electromagnetic
Premium Electron Photon Optics
An electron microscope is a type of microscope that produces an electronically-magnified image of a specimen for detailed observation. The electron microscope (EM) uses a particle beam of electrons to illuminate the specimen and create a magnified image of it. The microscope has a greater resolving power than a light-powered optical microscope‚ because it uses electrons that have wavelengths about 100‚000 times shorter than visible light (photons)‚ and can achieve magnifications of up to 1‚000‚000x

*Compound Interest/Discount* Compound Interest When you borrow money from a bank‚ you pay interest. Interest is really a fee charged for borrowing the money‚ it is a percentage charged on the principle amount for a period of a year - usually. If you want to know how much interest you will earn on your investment or if you want to know how much you will pay above the cost of the principal amount on a loan or mortgage‚ you will need to understand how compound interest works. * Compound interest
