- A microscope that has a total magnification of 1,500× when using the oil immersion objective has an ocular of what power? a. 150× c. 15× b. 1.5× d. 30×1. A microscope is turned on, under low power, with a slide positioned on the stage ready to focus. The specimen is visible but not in focus at all. - write the correct procedural steps used to find and focus on the specimen under medium power.what is bibulous paper used for? a. bleaching the benchtop b. cleaning microscope lenses. c. creating white flags of surrender d. drying slides.
- True or False: Ultrathin sections are used for light microscopy but are to thin to be stable under an electron mocroscope X-ray beam.Can someone answer and explain the following? What are the basic components of a Fluorescence Microscope and what are the functions of each? Are there any parts that you can remove without compromising accuracy and utility of the equipment? Can you suggest additional components to improve the equipment?It is desirable that the microscope objectives be parfocal because the specimen will be .................. a)blurry due to the changes in the refractive index of the medium b)stay in focus when the light is turned off c)have more contrast and enhanced details d)remain in focus if the magnification is changed e)none of the answer choices
- As with standard phase contrast microscopy,differential-interference contrast microscopy depends on differences in the ___________________ of a speciment to create high-contrast images. a. refractive index b. light absorption c. natural fluorescence d. walls and coverings e. natural pigmentation1. Differentiate the compound light microscope from the dissecting microscope in terms of: *image produced *magnification *type of specimen examined 2. Write down the principles of the following: *electron microscopy *scanning tunneling microscopy *atomic force microscopyA 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?
- Which microscopy technique is BEST at determining the presence of physical microbial interaction(s)? a Light microscopy. b Scanning or transmission electron microscopy. c Fluorescent microscopy. d Phase contrast microscopy.Previous question: For example, you can estimate the field of view diameter at 400x total magnification using the measured diameter at 100x total magnification. The magnification is 4 times greater so the field of view will be 4 times smaller. What is the field of view under the 40X objective of the microscope. - The Answer I got for this question was 3/4mm.The resolution of a microscope could be increased by raising the condenser to its highest point. True or False
