generating a projection

What are the differences between a light microscope and a dissection scope? ✅1. The
compound microscope uses only transmitted light, whereas the dissecting microscope
uses transmitted and reflected light so there won't be shadows on the 3D subjects.

2. Each eye has its own objective in the dissecting microscope so that 3D objects can
be seen as 3D, whereas the compound microscope has two oculars, but only one
objective for both eyes.

3. Compound Microscopes have greater magnifications, but lower resolutions than the
Dissecting microscopes.

What are the differences between a scanning electron microscope and a transmission
electron microscope? ✅Rather than the broad static beam used in TEM, the SEM
