Optical microscope

Discussion: When objects are placed under the microscope, it appears upside down and backwards. In part A, the letter E is placed right side up. But, when viewed through a microscope it looks as if it was placed upside down and backwards. In part B, the cotton strands with low power appears sharper when there is less light from the diaphragm. This is because with less light there is a sharper focus and when there is too much light coming from the diaphragm, the object can get blurry and out of focus

it easier to distinguish the different cells from one another. Moreover, the biologists could see specs within each of the cell's cytoplasm, probably resembling its various organelles. After drawing what they observed through the compound light microscope, the scientists moved onto the dyed and undyed onion cells. Under 400x, the scientists discovered

Light Microscope, Transmission Electron Microscope and Scanning Electron Microscope work; Evaluate the advantages and disadvantages of each type of microscope. The three different types of microscope all work very differently. They all have limitations as to what can and cannot be seen through them and two key factors as to why this is are magnification and resolution. Magnification determines how closely we can look at the object, whereas resolution presents the limits of the microscope as to what

the microscope. One of the first to use a microscope to observe microorganisms was Robert Hooke, the English biologist who observed algae and fungi in the 1660s. In the 1670s, “Anton van Leeuwenhoek, a Dutch merchant, constructed a number of simple microscopes and observed details of numerous forms of protozoa, fungi, and bacteria” (Introduction to Microscopes, n.d.). During the 1700s, microscopes were used to further explore on the microbial world, and by the late 1800s, the light microscope had

argument can also be made for the Glass Age. Throughout this course we have covered many topics while using a wide variety of equipment and technology all made possible through the advancements of glass. From window panes absorbing UV radiation, microscope lenses or eye glasses, to the fiberoptic cable that keeps us in an information age. Todays world would not be possible without glass. The first manmade glass was discovered in eastern Mesopotamia around 3500bc. Around 2000 years later glass vessels

Using a microscope to view living cells Introduction Living cells are the most basic unit of life, however, they are impossible to see without the magnification of a microscope. There are different types of microscopes with alterations to serve a specific function, but the general use is the same. It is a tool invented with a curved lense that magnifies things that cannot be seen with the naked eye. A microscope can be used to see many things, in this particular lab they were used to observe cells

telepathology. There is no secret that the current system has problems, including incompatibility within systems, and the expensive microscopes that are dedicated to telepathology, but future developments are being researched and produced to help offset the high costs. Low-cost internet solutions, videoconferencing, integrated digital pathology workstations, and virtual microscopes are just a few of the developments in the works. Low-Cost Internet Solutions One of the most ideal situations for the future

Introduction: When viewing live specimens with the microscope it can be very difficult to see. What makes slides hard to examine is the contrast between a cell and its background, which are both primarily water. In order to provide information and characteristics about the chemistry of a specimen a method called, staining is used to increase its differences. Stains/dyes are a salt that colors the ion it penetrates. There are two types of colors retrieved when staining; in a basic stain the color

Report #1: Using a Compound Microscope Section: 5 Objective: What is the proper way to use a compound microscope and prepare a wet-mount slide? Hypothesis: A compound microscope is being used properly when the light source, nosepiece lens, and eyepiece lens work together to bring a magnified image to one’s eye. A wet-mount is properly prepared when a drop of liquid containing the sample is placed between the slide and a thin glass coverslip. Materials: Compound Microscope Lens Paper Prepared Slide
