answered to pass
Microscope - correct answer ✔✔universal image of forensic science
Simple Microscope - correct answer ✔✔
Compound Microscope - correct answer ✔✔dual lens system
transparent light
40x-400x magnification
biological materials
isotropic materials
What are the components of a microscope - correct answer ✔✔
Polarizing Light Microscope - correct answer ✔✔uses filters to divide light into 2 parts (2 rays)
rotatable stage
anisotropic materials
crystal orientation identification
Refraction - correct answer ✔✔bending of light through a translucent material
Isotropic - correct answer ✔✔Materials with the same optical properties in all directions.
includes all gases, liquids, and certain solids
, Anisotropic - correct answer ✔✔Materials have varying optical properties dependent on the
orientation to the light.
Includes 90% of all solids
Real Image - correct answer ✔✔-Inverted from the object
-object is enlarged on the opposite side
-exists in real space
Virtual Image - correct answer ✔✔-only seen when looking through the lens
-It is on the same side as the object and goes in the same direction as the object (erect)
Birefringence - correct answer ✔✔-This results when anisotropic material is exposed to crossed
polarized light
- the difference with respect to the thickness of the material
Interference Colors - correct answer ✔✔-2 rays of light split by anisotropic material
-Interferes destructively or constructively
Pleochroism - correct answer ✔✔variation in the material's absorbance of light as opposed to
refractive index (RI)
Michel-Levy Chart - correct answer ✔✔banding patter of repeating color (interference)
variation to thickness of material
How do you figure the total magnification of a compound microscope? - correct answer
✔✔Magnification of lens 1 multiplied by the magnification of lens 2
