FIS 206 – Exam 1 Study Guide and Practice Questions
Simple microscope - ANS✔✔ light microscope consists of single lens used to produce an
enlarged image
Difference between real and virtual image? - ANS✔✔ with a lens it produces an enlarged image
which isn't real (ex: image of you in mirror)
Virtual image - ANS✔✔ it disappears when you stop looking through a lens, only exists in eye of
viewer (not in real space)
real image - ANS✔✔ could be projected onto a screen, exists at a definable. point in space.
Does not depend on looking through a lens
Compound microscope - ANS✔✔ has 2 stages of magnification
How do you find the total magnification of compound microscope? - ANS✔✔ product of
magnification of first and second lens
Components of a microscope - ANS✔✔
What is polarizing light microscopy? - ANS✔✔ exploits optical properties of materials to
discover details about the structure and composition of materials
refraction - ANS✔✔ bending and slowing of light as it passes through a medium
isotropic - ANS✔✔ materials demonstrate same optical properties in all directions
