QuestionAnswer
what are the 4 lens red (scanning) 4x yellow (low power) 10x blue (high power) 40x white (oil immersion) 100x
What is the optical part of the microscope? objective lens
what is the function of the condenser? allow more or less light in
Why is the function of the iris diaphragm.? controls light intesity
What part of the human eye does the iris diaphragm compare too. iris
why is oil used between the specimen and the oil immersion objective? increases power of the microscope. keeps light in by bending it.
Define parfocal lens that stays in focus when magnification focal length is changed
define resolution shortest distance between two points on a specimen that can be distinguished.
define working distance between lens and slide
define magnification refined power (enlarge object)
define field of view? observable area seen though lens
define ocular lens that magnify 10 times
define revolving nosepiece rotates to change from one objective to another.
define objectives? lenses of 4 difference magnification
define slide holders spring-loaded portion allows placing the slide in the mechanical stage where it is tightly held
define diaphragm lever opens and closes diaphragm to control amount of light striking objects
define condenser condenses light waves into pencil-shaped cone, thereby pre venting escape of light waves; also controls amount of light striking object.
define condenser adjustment raises and lowers condensers
define mechanical stage allows the slides to be moved
define mechanical stage controls moves the slide on two horizontal planes
define base supports the entire microscope
define arm used in carrying the microscope
define coarse adjustment moves stage up and down very slowly for approximate focusing
define fine adjustment moves stage up and down for purposes of definitive focusing
define body tube supports upper portion of microscope
at which point (power of magnification) can bacterial morphology ne determined? why? 1000x to clearly see shape/ inside structures
what type of microscope would you use to observe a stained bacterial smear compound light microscope
what type of microscope would you use to observe a virus scanning electron microscope (SEM)
what type of microscope would you used as a diagnostic tool for tuberculosis florescent microscope
what type of microscope would you use to observe the inside details of living microorganisms light microscope
what is the equation for calculating final magnification of an image> objective lens x ocular lens = final magnification.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
