Types of microscope and their uses?
Compound microscopes can be found in most biology and science classrooms. They are electrically operated and use light to enhance the image of a cell. They will have multiple lenses for viewing.Dissecting microscopes are also known as stereo microscopes. They have low magnification and are also light powered. These microscopes can view objects larger than what a compound microscope is able to handle, in three dimensions.Scanning Electron Microscopes use electrons instead of light to create an image. These microscopes produce three-dimensional images with high resolution and magnification. They also have a larger depth of focus.Transmission Electron Microscopes use electrons instead of light to create an image. The material prepared must be very thin. The beams of electrons that pass through it give the viewer high magnification and resolution. These give two-dimensional images.Electron microscopes are one of the most advanced microscopes used today. This microscope is powered by a beam of electrons with very short wavelengths. These electrons strike objects that come in its path and helps increase the resolution of the microscope. The electron microscope is one of the types of microscopes used to study cells like tiny viral cells as well as larger molecules.
What do sem and tem have in common?
Scanning electron microscopes and transmission electron microscopes use beams of electrons instead of light (light has a wavelength which gives a poorer resolution, as it is so big). The electron beams have very short wavelengths so the electron microscopes have higher resolutions (because the short wavelength means that the wave can pass through gaps that are too small for light waves to pass through. Because electrons are negatively charged the beam can be focused using electromagnets. Each EM microscope must have a vacuum in its chamber to work effectively because otherwise molecules in the air would interact with the electrons. Because of this living specimens may not be observed. A staining process is required for both The specimen must be extremely thin for both
Why can't you view living cells through electron microscope?
"In electron microscope the object is viewed in highly vaccum conditions. Living cells would disentegrate in such a condition." This answer is not mine it comes from the "why can't electron microscopes be used to view cell structures" question
How do the tree protect us from the sun's beams?
Their leaves are opaque there protect us from direct sunlight, that being a reason a tree has a shadow, that keeps us cool during hot weather.
Microscopes produce images by focusing light rays and beams of?
light
What is the difference between electron microscopes?
Electron microscopes and what ... Light microscopes produce magnified images by focusing visible light rays. Electron microscopes produce magnified images by focusing beams of electrons
Do microscopes produce images by focusing light rays and beams of heat?

What is the difference in the way light microscopes and electron electron microscopes produce images?
light microscopes allow light to pass through the specimen and use two lenses to form an image. Electron microscopes use beams of electrons, rather than light, to produce images.
Light microscopes use beams of electrons to produce magnified images?
No, a light microscope uses focused light (photons) to produce a magnified image. An electron microscope uses beams of electrons to create a magnified image.
Is light microscopes use beams of electrons to produce magnified images?
No, a light microscope uses focused light (photons) to produce a magnified image. An electron microscope uses beams of electrons to create a magnified image.
What type of microscope uses beams of electrons to produce an image?
light microscopes
