1. I believe that the compound light microscope would be the best microscope to use in order to observe very small objects or organisms on a slide. First, this microscope can magnify objects up to 1000 times. Second, this microscope is typically used to observe cell size, shape, and general appearance. The best microscope to use in order to observe internal structure, is the transmission electron microscope. The reason for this is because this particular microscope can magnify objects up to 100,000 times.

2. The first job that uses microscopes are forensic specialists. Forensic specialists use microscopes to observe specimens such as blood, skin, or hair from crime scenes. Another job that uses microscopes is microbiology. Microbiologists

Base.

K. Fine focusing knob.

5. I believe the microscope that has been primarily used in this lab is the compound binocular light microscope.

6. A. The iris diaphragm is the part of the microscope that controls how much light enters the condenser.

B. The ocular lense magnifies the image which is formed by the objective lens.

C. The condenser is the part of the microscope that focuses light through the specimen being observed.

7. A. The function of a diopter on a microscope is to fix the difference between both eyes so the image is clear.

B. The interpupillary distance is the distance from the center of one pupil to the center of the other; the distance between oculars. Correcting this distance will make the images one when looking through a microscope.

8. In order to find the total magnification of a compound microscope with an objective lens of 10X and an ocular lens of 4X, I believe you have to multiply the two. With that being said, 10x4=40X.

9. Coverslips are used to observe specimens under microscopes in order to protect the objective lense from being contaminated by the specimen being observed. Also, coverslips help keep the specimen in

A. After observing the letter “e” with the virtual microscope, it appears to be backwards and perhaps upside down. Compared to its appearance in the newspaper, the letter “e” is more transparent looking and not completely filled in. In a newspaper the letter “e” looks more dark and full.

B. The lenses on the microscope invert the image causing it to look reversed. With that being said, if the slide is moved to the right with the mechanical stage, the specimen will move left.

11. I was able to see the sequence of the of the colors more clearly when I transitioned from 4X magnification to 10X. At 40X magnification I wasn’t able to see much except the colors blurred together.

12. I noticed a few differences in in the various tissues/organelles, such as color and structure. For example, the plant epidermis was a teal color with a purple nucleus, and the spirogyra was more of a green color with a brown colored nucleus. Next, the plant epidermis had a structure that was more close together. On the other hand, the spirogyra had a structure that wasn’t as close together and more spread

    For part A, a graph plotting the charge over the capacitance was created and the slope identifying the experimental voltage was found to be 4.74 V. A discrepancy of 5% was found by using the discrepancy formula D=(exp/th-1)×100% with a theoretical voltage of 5.0 V. In addition, the graph plotting the charge over the voltage was created and the slope identifying the experimental capacitance was found to be 0.95 μF. A discrepancy of 5% was found using the discrepancy formula with a theoretical capacitance of 1.0 μF. For part B, two capacitors in a series had a calculated equivalent capacitance of 0.26 μF, found using the formula Q=C×V. The theoretical capacitance of 0.25 μF was calculated using the formula 1/C_s =1/ C_1 +1/C_2 and a discrepancy…

    Horizontal sweep is a term referring to the action of the horizontal system causing the glowing dot to move across the screen. Triggering the horizontal system causes the horizontal time base to move the glowing dot across the screen from left to right within a specific time interval. Many sweeps in rapid sequence cause the movement of the glowing dot to blend into a solid line. At higher speeds, the dot may sweep across the screen up to 500,000 times each second. Together, the horizontal sweeping action and the vertical deflection action traces a graph of the signal on the screen.…

    After 5 minutes, the glass slide was then placed and clipped onto the microscopic stage for examination. By adjusting the condenser focus knob and the fine focus knob, it was easy to view the visibility of the aquatic plant through the binocular eyepiece. The total magnification used to view the specimen was 100x; eyepiece was 10x and the object lens was set at 10x. To determine plasmolysis of the aquatic plant, the experimental glass slide was compared to the control to see the difference in change. After examining the slides, my partner and I have decided to set our minimum threshold for plasmolysis of the aquatic plant, Riccia fluitans, to 30%.…

    II INTRODUCTION The purpose of this lab was to demonstrate and observe the effect a large focal spot and a small focal spot will have on the resolution of the image. Chapter 3 of Practical Radiographic Imaging states that resolution is “the ability to distinguish two adjacent details as being separate and distinct from each other” (Carrol, 2007, p. 48). This definition of resolution helps to explain what will be looking for to retrieve the data for this lab. As stated in Chapter 16 of Practical Radiographic Imaging, the focal spot is defined as “the area on the x-ray tube anode which x-rays are emitted from, as seen from the viewpoint of the film” and this area can be determined by “the width of the beam of electrons striking the anode and by the bevel or angle of the surface of the anode where the electrons impact” (Carrol, 2007, p. 239).…

    X-rays and other radiological techniques aid in showing bones structure and mass in vivo. This is possible due to x-rays passing unobstructed through low density tissues and being obstructed by high density tissues. Goniometers are a tool used to measure the range of motion of a joint. This helps identify the plane of movement through which a bony landmark can be moved.…

    The stereomicroscope comprises of two compound microscopes which are adjusted one next to the other at the right visual edge to give a genuine stereoscopic picture. The long working separation (space between the example and target lens), upright nonreversed picture and expansive field of perspective settle on these the instruments of decision for performing preparatory examinations of confirmation and also controlling little particles and filaments to set them up for more point by point microscopical or instrumental investigations or correlations. An extra favourable position which comes about because of the long working separation and enlightenment by reflected light is that examples once in a while require any specimen arrangement. The example is basically set under the magnifying instrument and watched (Brown & Davenport,…

    Microscopy is one of science’s greatest innovations. The microscope has revolutionised countless areas of scientific research and has become an icon of science itself. From Anton van Leeuwenhoek discovering micro-organisms in the 1670’s to the highly powerful atomic microscopes used today, microscopy has furthered scientific knowledge in many, many ways [1]. It has practical applications in very many areas of research such as biotechnology, materials science, microbiology, environmental science etc. Its wide array of uses is reflected by the many different types of microscope e.g. compound microscopes, electron microscopes, fluorescence microscopes etc.…

    The SEM produces a largely magnified image by using electrons instead of light to form an image. A beam of electrons is produced at the top of the microscope by an electron gun. It consists of an electron gun to produce high energy electron beam. A magnetic condensing lens is used to condense the electron beam and a scanning coil is arranged in-between magnetic condensing lens and the sample. The electron detector (Scintillator) is used to collect the secondary electrons and can be converted into electrical signal.…
