An opaque object requires _________illumination
for viewing with a microscope
Step by step
Solved in 3 steps
- The diffraction limit is an unbeatable barrier limiting the effective resolution of light microscopy due to the inherent wavelength of light.True or FalseA microscope that remains in focus regardless of whichobjective lens is rotated into place is __________.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 pigmentation
- 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.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.Of the four major types of microscopes, give an example of a scenario in which each would be the ideal choice for visualizing a sample. Stereo (Dissecting) Compound Confocal Electron
- Sal said that the microscope had a total of 400x magnification because the eye tube had a level of 10x and the objective lens had a magnification of 40x. Is sal correctHow can a UV-Vis spectrophotometer be applicable in determining the absorbance/concentration of a colorless sample? Please answer in detail and clearly. Thank you so much!True or false : each objective of a phase contrast microscope contains a phase plate. phase contrast microscopy relies on the condenser to increase the contrast of an image. in brightfield microscopy, closing the condenser aperture will decrease the contrast of the speciment. stained cell speciments are best viewed by phase contrast microscopy.
- The resolution of a microscope could be increased by raising the condenser to its highest point. True or FalsePrevious 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.When trying to focus an object on the microscope, you always begin with the ________________ objective lens and use __________________ adjustment knob to bring the object in focus. Once object is focused, high power objective lens can be used to magnify the object, and only use the ___________________ adjustment knob to focus at this point. a scanning; coarse; fine b low power; coarse; fine c low power; fine; coarse d scanning, fine; coarse
