- identify these parts of the microscope I have submitted these answers but there were 4 wrong 1.Ocular lens2.Diopter Adjustment3.Nose piece4.Stage5.Condenser6.Iris diaphragm7.Illuminator8.Course objective knob9.Fine adjustment knob10.Objective lensPlease answer the following questions (Question 1 AND 2) about compound microscopes. After clicking the objective into position, which adjustment knob(s) can you use to safely refocus the image? You may need to adjust the light intensity to better see the specimen. Indicate two ways in which you can change the light intensity?A lab revolving around compound microscopes was conducted. Please answer the following questions (questions 1, 2, and 3). If a specimen (placed on a slide) has little or no color, what level of light intensity should you use; should the intenisty of the light be high or low (choose)? Which objective should be in position before you start to focus the microscope? Which focus knob should you use first with this objective?
- Write the term that the phrase describes. 1. Large knob that moves the stage or objective lens a great distance. Used with scanning or low-power objective lenses only. 2. Flat platform beneath the objective lens on which the microscope slide is placed. 3. Removable lenses that you look through to observe the microscope slide. 4. Small knob that moves the stage or objective lens a very small distance and is used for precision focusing. 5. Extends from the arm and contains the ocular lenses and rotating nosepiece. 6. Lens that condenses light through the specimen and is located below the stage. 7. Light from specimen passes through these lenses first. These lenses are located in the rotating nosepiece. 8. Wide bottom part that supports the microscope. 9. Regulates the amount of light passing through the condenser. 10. Vertical portion that connects the base to the head.Match each item with the correct compound light microscope part below. objective lenses fine adjustment knob diaphragm 1. choice D 2. choice K 3. choice GWhat part of the microscope is used to make small-scale adjustments to the height of the stage?

- How will the following affect resolution during microscopy? I) Closing or opening the diaphragm II) Raising or lowering the condenser III) Increasing or reducing the light intensityplease help me make this procedure a flow chart III. Procedure: A. MicroscopyOperating Procedure:Place the microscope close to the edge of the table. Select a suitable stool so that when looking into the eyepiece, your back is straight and your neck is bent at the nape.1. Lower the body tube by turning the course focus knob until the 10x or 16mm objective reaches the downward stop.2. Look through the eyepiece and adjust the mirror to the position which provides the brightest and the most evenly illuminated field of vision which is the circular area seen in the eyepiece. Raise the condenser until its top lens at the same level as the stage. Place the slide on the stage and fasten it using the stage clips.3. Position the specimen area of the slide over the center of the stage aperture.4. Looking through the eyepiece, raise the coarse focus knob until the image appears. Focus as sharply as possible. Low power objective has a much greater depth of focus and is generally used for the…Complete the following table by calculating the total magnification of the different objectives of the microscope with the given eyepieces.
