Does SEM microscope produce 3D image?
No it doesn't , but you can make 3d image by taking three or four 2D scans of titled sample and then using image processing reconstruct it in 3-D
Why is it dangerous to focus using the coarse adjustment knob for on a microscope when using high power?
It can burn your eye.
How does a confocal laser microscope work?
A confocal laster microscope works by using optical sectioning, whereby the laser acquires different images and they are put back together to produce one image on a computer. This process enables a much more intricate finished image.
Compare and contrast a compound light microscope and an electron microscope?
Light microscope: 1. Uses a beam of light that is focused using glass lenses. 2. Magnification is moderate -- not as much as electron microscope 3. Produces a color image since it uses light 4. Can look directly at the specimen with our eyes Electron microscope 1. Uses a beam of electrons that is focused using magnets. 2. Magnification can be extremely high and show details that are not possible with the light microscope 3. Produces a grey-scale image because color requires visible light 4. Image must be seen on a monitor or in a photograph because we don't see electrons.
What is the difference between a Light Microscopes and an Electron Microscope?
The optical microscope is the most common. It uses light to image a sample that is too small to be seen by the naked eye.The scanning electron microscope examines the surface of objects using an electron beam and measuring reflection.Short Answer = Resolution.
Why Images observed under the light microscope are reversed and inverted?
The microscope you are using is probably old, and it has an odd number of convex lenses between the object and your eye. in addition to enlarging (or reducing) an image, an optical convex lense also inverts the image. If you were to invert the inverted image again, using another lense, then the resulting image will appear upright. So a microscpope with three lenses (most likely the number of lenses in the microscope you are using) inverts the image three times, resulting in an upside-down image. A microscope with four lenses shows an upgright image. That is why modern microscope manufacturers use an even number of lenses in a microscope (and in binoculars).
What can cause an image to appear blurred using a microscope?
The light so bright.
Which lens of a microscope is responsible for producing a magnified image on the inside of the microscope that is not seen directly by the person using the microscope?
to produce a magnified image, a microscope uses 2 convex lenses which have relatively short focal lengths to magnify small, close objects.
Is the image reversed when you looking at an object using the stereoscopic dissecting microscope?

How would you be able to distinguish part of the organism using the microscope?
Using high power objective lense
Why would using a microscope for observation be more advanced than using a simulated computer model?
Because a simulated computer model is based on historical data. A microscope gives you a 'real time' image.

What is the function of coarse focus adjustment knob on the microscope?
The function of a microscope's coarse adjustment knob is to improve focus on the object under study by adjusting the lens. Unlike the fine adjustment, coarse adjustment moves the lenses quickly.
What is the difference between an electron and a light microscope?
A light microscope is a simple microscope that magnifies light that it collects and spread onto a screen digitally or optically. Electron microscopes is a microscope that fire electrons onto a object then it is bounced back to form an image. It enlarges the image when it is bounced back. It is fired consistently to receive a constant image. It is viewed with a electronic screen. When the electron is fired it creates light which bounces back as well. It can magnify much bigger than a optical microscope.
