Intro to Micro

Shortest lens is Scanning

Low-power objective is Medium

High-power is Longest

Ocular Magnification: 10

Scanning Objective: 4

Low-Power Objective: 10

High-Power: 40

Total magnification: multiplying the objective lenses with ocular lens

Diaphragm Range: 1-100

Line inside microscope is for?: Focus on object

What are the most likely explanation for the perfect circles that are completely clear with a thick black outline?: Air bubbles

Microscope flips specimen

To move to right: move slide left

To move to left: move slide right

To move slide away: move towards

To move up: move down

To move down: move up

NEVER USE COURSE ADJUSTMENT KNOB ON HIGH POWER

Magnification Increase: field area for viewing gets smaller

Why must specimen be centered before switching from low to high power?: Remains in view when looking through microscope

Top: Red

Middle: Blue

Bottom: Yellow

F: On high power, you should use the course adjustment knob

T: The diaphragm determines how much light shines on the specimen

T: The low power objective has a greater magnification than the scanning objective

F: The fine focus knob visibly moves the stage up and down

T: Images viewed in the microscope will appear upside down

T: if the slide is thick, only parts of the specimen may come in focus

F: For viewing, microscope slides should be placed on the objective

T: In order to switch from low to high power, you must rotate nosepiece.

F: The total magnification of a microscope is determined by adding the ocular lens power to the objective lens power.
