How has the use of the binocular microscope contributed to the study of science?

What are microscopes? Make a  brief  outline   of the history   of  microscopes? Relate microscopy with our present status  in  the scientific  and  economic  world. What are  wet  mounts? How to prepare  wet mounts? How to remove   water  bubbles  in  wet mounts? What are the  steps  in manipulating  /  focusing  the  microscope? What are the  reminders  before  storing  the microscope? How many times  an object is enlarged  when  a) HPO is used LPO is used Oil immersion objective   a. when to  use     the coarse  adjustment    knob? when   to use  the  fine  adjustment  knob if given the chance  to manipulate  the  microscope, what  particular    specimen would  you like  to see  first .

What description best describes the compound light microscope? Uses a beam of electrons is transmitted through a specimen to form an image. Has more than one lens and its own light source. In this type of microscope, there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen. An optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation. Designed for low magnification observation of a sample, typically using light reflected from the surface of an object rather than transmitted through it.

If you were trying to visualize living organisms without staining, which type of microscopy would be best to utilize? O 1) brightfield O 2) TEM 3) fluorescent O 4) confocal O 5) phase contrast

PRELAB: Calculating Magnification Each lens makes the object look larger by a specified amount. To determine the total magnification, multiply the magnification of the eyepiece and the objective being used. Table 1: Microscope Magnification Magnifying power Objective Objective Eyepiece Total name Scanner 4 X Low power 100 X High power 40 χ PRELAB: Estimating the Size of an Object using a Microscope You will not be able to use a ruler to directly measure the size of a cell. Instead, you will use an indirect method by comparing the cell to the size of something you already know. The diameter of the microscope's field of view as seen through the eyepiece is a convenient length to use. A very small unit of measurement, the micron (µm) is used for measuring microscopic objects. The conversions are: 1 um = 0.001 mm 1 mm = 1000 µm Table 2: Field of View Diameters Objective Diameter name millimeter (mm) micron (um) Scanner 4 Low power High power 0.5 To estimate the size of an object, divide…

make a comparison viewing a microscope slide under low magnification and high magnification by identifying benefits and drawbacks for each.

Put the steps for using a microscope in order.    While looking through the eyepiece, use the coarse adjustment knob to  bring the object roughly into focus.  Lower the stage as far away from the objectives as possible.  Use the fine adjustment knob to bring the object into sharp focus.  Turn on the light.  Place the slide on the stage and center it.  Turn the nosepiece to the lowest power objective.

The field of view is the maximum area visible through the lenses of a microscope, and it is represented by a diameter. To determine the diameter of your field of view, you can place a transparent metric ruler under the low power (10X) objective of a microscope. You would focus the microscope on the scale of the ruler and measure the diameter of the field of vision in millimeters. Refer to the image taken of this preparation below. What is the approximate field of view as seen by this 10X objective. Note: This microscope has a 10X eyepiece, giving a total magnification of 100X. 0000 1mm 2mm 3mm 4mm 1mm

Give three examples of organisms or phenomena for which observation by phase microscopy might be preferable to bright-field.
