Conventional light microscopes have long been limited in resolution to around 200 nm in width and 500 nm in depth due to the nature of light diffraction. Imaging at much greater magnifications would have required the use of electron microscopes. However, resolution down to tens of nanometers in...
Electron Microscopesuse an electron beam (instead of a light beam) to produce an image of the sample; because the wavelength of an electron is around 100,000 times shorter than that of a photon of light, images can be viewed with a resolution down to around 50pm. Scanning electron microsc...

How are primary waves and secondary waves alike? In the Bohr model of the atom, what is true about the light emitted by an atom? 1. The energy of the emitted photon is equal to the difference in energy between the two orbits. 2. An electron accelerating around its orbit...
Initially, the biologist selects a particular part of an organ which should be studied. Then using an appropriate stain, he stains the tissue and mounts it on a microscopic slide. Next, using a light or electron microscope, he examines the stained tissue under the microscope and records the ...
