Answer 1

Simple Microscope

Question 2

It means “to look at”

Answer 2

Skopein

Question 3

What are the two-lens system?

Answer 3

Ocular Eyepiece and Objectives

Question 4

It is turned on by the main switch and can be replaced with either a mirror or LED lamp

Answer 4

Light Source/Illuminator

Question 5

It is located between the mirror and the stage; it is considered a lens but is not a magnifying lens

Answer 5

Condenser

Question 6

It is only found in a binocular microscope since it controls the distance of eyes

Answer 6

Interpupillary Distance Adjustment

Question 7

It raises/lowers the condenser

Answer 7

Condenser Adjustment Screw

Question 8

Ring around condenser that you can rotate

Answer 8

Iris diaphragm Ring

Question 9

Name the 2 feed knobs in the mechanical stage control knobs

Answer 9

X-axis (horizontal)
Y-axis (back and forth)

Question 10

It is located inside the condenser and it is important because of its role in balancing and adjusting the intensity of the light

Answer 10

Iris diaphragm

Question 11

Name the 2 Focus adjustment knobs

Answer 11

(1) Course Adjustment Knob (up and down)
(2) Fine Adjustment Knob (for focusing)

Question 12

It is the science of microscopic techniques that ends with scientific laws

Answer 12

Principle of Light Microscopy

Question 13

It is the total of times the final image is magnified

Answer 13

Total Magnification

Question 14

Also called an Intermediate Image

Answer 14

Real Image

Question 15

It is synonymous with clarity and has the ability to separate 2 clear objects. Often expressed as revolving power

Answer 15

Resolution

Question 16

Resolving power of an Eye

Answer 16

0.1 mm

Question 17

Resolving power of light microscope

Answer 17

0.2 mm

Question 18

The object is placed within focal distance and is not reversed

Answer 18

Virtual Image

Question 19

It says if the image is magnified or not

Answer 19

Focal Length

Question 20

It is the light-gathering ability of an optical at a fixed object distance

Answer 20

Numerical Aperture

Question 21

(T or F) The lower the resolving power of the objective; the clearer the image

Answer 21

FALSE (The greater the resolving power)

Question 22

It is the amount of object that can be seen with a partial optic combination

Answer 22

Field of View

Question 23

(T or F) The lower the focal number, the lower the viewable area

Answer 23

TRUE

Question 24

(T or F) At a resolution higher than 2,000 the image becomes degraded hence having an empty magnification

Answer 24

TRUE

Question 25

What is the dry imaging medium?

Answer 25

Air

Question 26

(T or F) Resolution is Synonymous with Clarity

Answer 26

TRUE

It is the type of microscope where the organelles can be seen

Answer 29

Electron Microscope

Question 30

It is the refracting Image

Answer 30

Eta

Question 31

It reduces eye fatigue

Answer 31

Interpupillary distance adjustment

Question 32

(T or F) The smaller the value; the greater the Resolution

Answer 32

TRUE

Question 33

It measures the comparative velocity of light in different media

Answer 33

Refractive index

Question 34

(T or F) The bi-convex magnifier lenses are thinner at the center than at the periphery

Answer 34

FALSE (Thicker)

Question 35

(T or F) The field of view increases when the magnification is increased

Answer 35

FALSE (the field of view decreases)
