An electron microscope requires that the subject be dead to function. In order to receive a picture, the specimen must be coated in chemicals and put into a vacuum, a process which will kill any living specimen. A light microscope, although not as detailed, will allow the scientist to observe living specimens.
no but she had training
To examine it under the microscope, the specimen needs to be illuminated by either a light underneath or a stream of electrons. If the specimen is too thick, and light or electrons cannot penetrate it, the scientist will be unable to see any detail.
no
Any object you can see reflects light. If it did not reflect any light it would be invisible. Similarly, no object is so reflective that it reflects all light. The proof that it absorbs light is that it increses in temperature as it is exposed to light.
An electron microscope would be needed to see detailed images of an internal structure of a bacterium, as it can provide much higher magnification and resolution compared to a light microscope. The electron microscope uses a beam of electrons instead of light to visualize the specimen, allowing for better visualization of internal structures at the cellular level.
Using a microscope is fairly simple, once you have been shown the ropes. However, interpreting and analyzing what you are seeing will take longer. Medical Technology, for example, is a four year degree.
no you do not need any special training you will be taught in college!
Any organic substance or sample thin enough to let light through.
yes you do need light to so things in microscope------------------------In a compound microscope the light is transmitted through the object therefore the object must be very thin to allow the light through. They are called thin sections and mounted to a glass slide.A stereo microscope uses incident light, bounced off of the object's surface.In either case, no light means no image.You can use electric light sources of many kinds; LEDs, halogen, incandescent, mercury vapor are just a few. You can use a mirror to reflect any kind of light including bright light from a window, a candle, a desk lamp, whatever.Phloem
You may need some training but it should not be a lot. You may need CPR training if they have a high suicide rate. You can talk to the employer about any special training you may need.
The conclusion in a light microscope refers to the final observations and analysis made after examining a sample using visible light. It summarizes the findings, identifies any patterns or structures observed, and may suggest areas for further research or exploration.

The light intensity control knob should be set to its lowest setting before turning the microscope off. This prevents the light from suddenly flashing at full intensity when the microscope is turned back on. When turning the microscope on, start with the light intensity set to low and gradually increase it to achieve the desired level for viewing.
A compound microscope can either have a light bulb or a mirror for illumination. If your microscope has a mirror, then you need sunlight or some other light source to point at the mirror to view your slide.The mirror is used to focus light up through the hole in the microscope's stage, or slide platform. The slides will contain a thin slice of material through which the light can shine, to reveal the internal structure of the sample.=========================================Mirrors on the exterior of microscopes are there to reflect ambient light (especially sunlight) under the slide being viewed to illuminate it. These are necessary for microscopes that don't have their own light sources.Mirrors in the interior of the microscope are there to redirect the optics and make the microscope more compact or to facilitate making the microscope binocular.
Yes
Viruses are extremely small, typically ranging from 20 to 400 nanometers in size, which is much smaller than what the human eye can see. In order to visualize viruses, an electron microscope is necessary because it uses a beam of electrons to create an image with much higher resolution than a light microscope.
