Summary Introduction
Introduction:
Various types of lights have been used in several classes of microscopes to examine specimens. The light microscopy is classified into four types based on the application of light on the image to get its appropriate view.
In transmission electron microscopy, a beam of electrons is generated to produce the image on a fluorescent background. It is used to study the internal details of a specimen.
The light microscopy and the transmission electron microscopy differ from each other on the basis of their magnification power, resolution, and wavelength.

Both (b) and (c) are correct. e. All are correct.arrow_forwardYou are trying to look at a specimen with a compound microscope using the 4x objective, but it is very dark. Mention three parts of the microscope you could adjust that would help see your specimen in this darkness. Explain how you would adjust those parts.arrow_forwardDyes are used to stain specimens that will be observed using the microscope to a. increase the magnification. b. increase resolution. c. increase contrast. d. make it visible. e. none of the above.arrow_forward
- Explain the differences that you have seen using types of microscopes such as scanning electron, low power, high power, and oil immersion.arrow_forwardIn light microscopy, when magnification is increased, the lens focuses closer to the sample. This makes the user more likely to ram the sample into the lens. Why is it common for the lens to focus closer to the sample at higher magnifications? What can be done to mitigate this risk?arrow_forwardBoth light and electron microscopy are commonly used to visualize cells, cell structures, and the location of specific molecules. Explain why a scientist may choose one or the other microscopy technique for use in research.arrow_forward
- 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 choicesarrow_forwardClinical Microscopy Label the parts & functions of a COMPOUND LIGHT MICROSCOPE How to set-up a microscope?
