The two main advantages of SEM over light microscopy is that the SEM has a much deeper depth of field and that it has higher resolution than a light microscope can achieve and the resultant much higher magnification from the SEM.
Light microscopes allow you to view living specimens and electron microscopes do not allow this.

The resolution had limitations of 200 nanometers.
Yes, electron microscopes have a much higher possible magnification than compound light microscopes. An electron microscope is capable of 10,000,000 times magnification, whereas a good compound light microscope is capable of 1,000 - 2,000 times magnification.

TEM gives 2D images and SEM gives 3D images.
Light microscopes allow you to view living specimens and electron microscopes do not allow this.
There are more than one type of light microscopes as well as other types of microscopes such as the SEM. The first microscopes were (and still being used) are the simple light microscopes. The compound microscope has that name because it contains two types of lenses that function to magnify an object. A simple microscope is a microscope that uses only one lens for magnification. It is the original design of the light microscope. Van Leeuwenhoek’s research used this type.
The advantages and disadvantages of the light microscope relate to light, magnification and resolution. Light microscopes magnify visible light--an obvious advantage, since this is what our eyes can see. Magnification (how large an object appears) and resolution (the clarity of details) are both limited when using light microscopes.
Two types of electron microscopes are the scanning electron microscope, or SEM, and transmission electron microscope, or TEM.

Light microscopes are called compound because a light microscope has more than one lense.

I know that electron microscopes kill cells and require chemical fixation but show a 3d image I know there is one type of electron microscope can see living cells
Scanning Electron Microscopes have a much larger zoom range. therefore the image from a SEM is more in depth. think of it as looking at a basketball from far away... you see an orange ball. but when you look at it upclose, you see the black lines and dimples on the ball. same goes for whatever your looking at under the SEM
