Microscopes use light to illuminate the stage where you place a slide for viewing. Without this light, you would be unable to see much of anything.
The light microscope use the visible light; the electron microscope use an electrons beam.
We use light microscope because it is better for our eyes!!
An electron microscope does not use a beam of light. Instead, it uses a beam of electrons to visualize specimens at much higher resolution than can be achieved with light microscopes.
A compound light microscope is named for the use of more than one lens to collect and focus light, and magnify the image.
IF YOU HAVE A MICROSCOPE THAT DOES NOT HAVE AN INTERNAL LIGHT SOURCE, YOU WILL HAVE TO USE THE EXTERNAL LIGHT SOURCE THAT IS PROVIDED IN THE CABINET WITH THE MICROSCOPE.
light mircoscope. you little study island fiend.
To view a tapeworm, you would use a light microscope. First, prepare a microscope slide with a sample of the tapeworm, then place it under a light microscope for viewing. This type of microscope allows you to observe the external and internal structures of the tapeworm.
You could use a stereo microscope, also known as a dissecting microscope, to observe organisms found in pond water. This type of microscope provides a three-dimensional view of larger specimens at lower magnifications.
When you want to look at things you couldn't with a light microscope.
True.
---- You would use the light microscope. The electron microscope would be unnecessary in this situation, due to its high magnification levels.
The transmission electron microscope operates on the same principle as the light microscope but uses electrons instead of light. What you can see with a light microscope is limited by the wavelength of light. Transmission electron microscopes use electrons as "light source" and their much lower wavelength makes it possible to get a resolution a thousand times better than with light microscope.
