Safety and Microscope

Question 1

Base of Microscope

Answer 1

gives stability to microscope

Question 2

Ocular/eye piece lens of Microscope

Answer 2

viewing lenses to see microscope slide images

Question 3

Neck/arm

Answer 3

holds eyepiece and nosepiece of microscope

Question 4

Objectives

Answer 4

has scanner, low, and high power; varies the magnification of slides

Question 5

Stage of Microscope

Answer 5

holds slide under objective lense, holds to be adjusted

Question 6

Stage Clips of microscope

Answer 6

secures slides on the stage under the objective lenses

Question 7

Diaphragm of Microscope

Answer 7

adjust the light given through the stage for the slide being viewed

Question 8

Light Source of Microscope

Answer 8

provides adequate light for a clear image of a slide while increasing magnification

Question 9

Coarse adjustment of Microscope

Answer 9

lowers and raises the stage, general focus

Question 10

Fine adjustment of Microscope

Answer 10

lowers and raises stage of microscope, used on 10x and 40x magnification for detailed image

Question 11

Nosepiece of Microscope

Answer 11

adjusts objectives to different levels of magnification

Question 12

Working Distance

Answer 12

the distance between the bottom of the objective lens and the stage

Question 13

Depth of Field

Answer 13

the distance in which the specimen appears to be in focus

Question 14

Field of View

Answer 14

the area that can be seen through the ocular lens, circle of light

Question 15

Resolution

Answer 15

the minimum distance in which two points can be separate and still be distinguished

Question 16

Monocular

Answer 16

scope only has one ocular lens for viewing specimens

Question 17

Binocular

Answer 17

scope has two ocular lens for viewing specimens

Question 18

What do you expect in terms of the working distance of the microscope when you use each? In other words, which one do you think has the shortest working distance?

Answer 18

I imagine from the scanner to low power to high power the magnification of an image will increase and the working distance will decrease; the high scanner has the smallest working distance

Question 19

Objective lenses magnification

Answer 19

scanner: 4x
low power: 10x
high power: 40x

Question 20

What do you expect in terms of the working distance of the microscope when you use each? In other words, which one do you think has the shortest working distance?

Answer 20

I imagine from the scanner to low power to high power the magnification of an image will increase and the working distance will decrease; the high scanner has the smallest working distance

the field of view decreases as magnification increases

Question 21

How do compound scopes work?

Answer 21

Compound scopes rely on a series of mirrors to refract light through the specimen; This results in an inverted
image; It also affects the direction the
image moves in the eyepiece when you move the stage!

Question 22

What are general requirements/protocols in the lab?

Answer 22

legs completely covered from head to foot, closed shoe with firm bottom, safety glasses for designated labs, proper attire

Question 23

What is the magnification of our ocular/eyepiece in Biological Foundations lab?

Answer 23

10x(multipled with eyepiece lens)
