4) Answer true or false to each of the following statements.On high power, you should use the coarseadjustment knob.The diaphragm determines how much light shines onthe specimen.The low power objective has a greater magnificationthan the scanning objective.The fine focus knob visibly moves the stage up anddown.Images viewed in the microscope will appear upsidedown.If a slide is thick, only parts of the specimen maycome into focus.The type of microscope you are using is a scanningmicroscope.For viewing, microscope slides should be placed onthe objective.In order to switch from low to high power, you mustrotate the revolving nosepiece.The total magnification of a microscope isdetermined by adding the ocular lens power to theobjective lens power.

False: On the high power ,you should use the coarse adjustment knob. It is false because use only…

The FOV on low power of a microscope is measured to be 4.5mm. Using the chart below and the above listed formulas calculate: FOvx = FOvlow X Maglow Magx S.S. = FOvx # times the specimen fits across the FOv Total Mag = Ocular lens x objective lens a) What is the FOV on High Power? (Magnification on High power is 40x) Can you please include the units too. asap please.
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 intensity
Which of these is NOT a best practice when using, handling, or storing a microscope and microscope slides? Do not touch the objective lenses. Store the slides in bright sunlight to prevent mold growth. Rotate the nosepiece to the lowest objective before storing the microscope. Keep dust away from the scope by covering it during storage.
A student using a microscope measured the low power field diameter to be 7.1mm. The student then switched from the low power (4x) objective lens to the medium-power (10x) objective lens. Assuming a 10 x ocular (eyepiece) lens, the medium power field diameter is ____ um um is micrometers
The compound (bright-field) microscope is parfocal. It means that: Question 4 options: objective lenses are built into revolving nosepiece its lenses effectively decrease focal lenght can achieve maximum resolution lower than 0.2 μm image should remain in focus when objective lens is changed
Complete the following table by calculating the total magnification of the different objectives of the microscope with the given eyepieces. OBJECTIVES OCULAR Designation Magnification Focal Length Numerical Aperture (NA) Final magnification with: 10x 15x 25x Scanner 4x 46mm 0.10 LPO 10x 16mm 0.25 HPO 40x 4mm 0.55 OIO 100x 1.8mm 1.30
Which of the following is a parameter of microscopy that can affect your ability to resolve a specimen using a compound light microscope? Question options: Contrast Resolving power All of the choices Numerical aperture
The objective lenses of the microscopes used in this course are all parfocal. What does having parfocal objective lenses mean? Question options: The slide has to be moved away from the objective lens (i.e., lowered) when switching between objective lenses. None of these choices The objective lenses have optimized light gathering capability. Once in focus, you may switch between objective lenses with only fine focus adjustment required.
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 lens
True or False: The microscope should be stored with the oil immersion lens in position over the stage. If this statement is false, correct the statement.
Match the lens (condenser, high-dry, low-power, ocular, or oil immersion) to itsdescription. Choices may be used more than once. This lens collects and focuses light from the lamp onto the specimen on the slide.
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.
