- Trace the path of light from the light source through the microscope in the correct order: O condenser, ocular lens, objective lens, specimen ocular lens, objective lens, specimen, condenser condenser, objective lens, specimen, ocular lens condenser, specimen, objective lens, ocular lens O ocular lens, specimen, objective lens, condenserTotal magnification of a microscope is determined by Multiple Choice dividing the objective magnification value by the ocular value. multiplying all objective magnification values together. adding all objective magnification values together. none of the above.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.
- Which of the following is true about the relationship between depth of field and magnification? There is no relationship. When magnification increases, depth of field decreases. When magnification increases, depth of field increases. Stereomicroscopes offer a lesser depth of field than compound microscopes. The depth of field of a microscope determines how much magnification it can achieve.Which of the following microscopes produce flat images by utilizing light in the non-visual spectrum to excite molecules within the specimens to produce visual light? (select all answers that apply) Phase Contrast Microscope Darkfield Microscope Fluorescent Microscope Brightfield Microscope Electron Microscope Confocal MicroscopeThe 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
- briefly describe the functions of the following parts of the microscope: course objective knob, condenser lens, diaphragm, objective lens, illuminator, fine adjustment knob, oil immersion.What is the highest magnification of the following microscopes?Bright fieldDark fieldPhase-contrastFluorescenceConfocalScanning EMTransmission EMScanned-ProbeAn object found with the 10x objective of the microscope may be viewed with the 40x objective without having to re-focus. This property of the microscope is called: O Confocal O Bifocal Binocular d Parfocal
- 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.What is the purpose of using microscopes? If you need to move the microscope, describe how you should carry it. What three things change as you increase magnification? On the compound microscope, what power must be in place when you first find an image in themicroscope? On the compound microscope, which adjustment knob is used for bringing the specimen intofocus? On the compound microscope, which adjustment knob is used for sharpening the image of thespecimen after it is focused? On the compound microscope, which adjustment knob should you use on the high power? On the compound microscope, how do you change the objective lenses? What should be included when sketching or drawing what is seen through the microscope How do you properly use a microscope?For a microscope that has an objective lens magnification of 100X and an ocular lens magnification of 5X, calculate the total magnification. 500X O 1000X O 50X O 100X O No listed answer is correct.
