| Question | Answer |
| what is microscopic ? | Objects that can only be seen using a microscope are described as microscopic. |
| What is microscopes ? | A microscope is a laboratory instrument used to examine objects that are too small to be seen by the naked eye |
| What is stereo microscopes ? | A stereo microscope is having two monocular microscopes joined together with each one focusing on the same point but from different angles. |
| what is a magnification ? | The magnification of the microscopes tells us how much bigger the image is than the real object. If the microscope has a magnification magnified by 10 then the image is ten times bigger than the actual object. |
| what is electron microscope ? | An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. |
| what is transmission electron microscopes ? | The transmission electron microscopes is used to view thin specimens examples : bacteria, cells, biological samples |
| What is scanning electron microscopes ? | A scanning electron microscope is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. |
| What is the difference between transmission electron microscope and scanning electron microscope ? | The main difference between SEM and TEM is that SEM creates an image by detecting reflected or knocked-off electrons, while TEM uses transmitted electrons that pass through the sample to create an image |
| What is photomicrography ? | A micrograph or photomicrograph is a photograph or digital image taken through a microscope or similar device to show a magnified image of an object. |
| What is light microscope ? | The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. |
| What is binocular microscope ? | A binocular microscope is any optical microscope with two eyepieces to significantly ease viewing and cut down on eye strain |
| What is binocular microscope ? | A binocular microscope is any optical microscope with two eyepieces to significantly ease viewing and cut down on eye strain |
| What is monocular microscope ? | Monocular microscopes, are microscopes that are equipped with one eye piece, can magnify samples up to 1,000 times. |
| What is the difference between monocular and binocular microscopes ? | Monocular microscopes are microscopes that are equipped with one eye piece that can magnify samples up to 1,000 times. While binocular microscopes is any optical microscope with two eyepieces that significantly ease viewing and cut down on eye strain |
| What is micrometre ? | A micrometre is one thousand of a millimetre or one millionth of a metre. It is the unit most often used by scientists to measure microscopic objects. |
| What are electron microscopes used for ? | Electron microscopy (EM) is a technique for obtaining high resolution images of biological and non-biological specimens. It is used in biomedical research to investigate the detailed structure of tissues, cells, organelles and macromolecular complexes. |
| What are stereo microscopes used for ? | The stereo microscope is often used to study the surfaces of solid specimens or to carry out close work such as dissection, microsurgery, watch-making, circuit board manufacture or inspection, and fracture surfaces as in fractography and forensic engineering. |
| What are magnification used for ? | Image result for what are magnification microscopes used for A microscope is something that uses a lens or lenses to make small objects look bigger and to show more detail. |
| What are the names found in a light microscopes ? | The bright light microscope has two sets of lenses, the objective lens and the ocular lens. The objective lens is directly above the stage, and provides the primary magnification |
| What are the difference between ocular and objective lenses ? | Ocular is the eyepiece and objective lenses magnifies with the help of the eyepiece. |
