He called them as -

Answer 14

animalcules

Question 15

Types of Microscope

Answer 15

Light Microscope
Electron Microscope
Flourescence Microscope

Question 16

Uses visible light and a series of lenses to magnify objects.

Answer 16

Light microscope

Question 17

Types of light microscope

Answer 17

Compound microscope
Stereomicroscope (Dissecting Microscope)

Question 18

Uses a beam of electrons instead of light to achieve much higher magnifications, up to millions of times. Used to observe VERY small objects: viruses, DNA, parts of cells

Answer 18

Electron Microscope

Question 19

Types of Electron microscope

Answer 19

Transmission Electron Microscope (TEM)
Scanning Electron Microscope (SEM)

Question 20

The most common type, which uses multiple lenses to achieve high magnification, typically up to 1000x. It’s used to view thin sections of specimens like cells and tissues. Light passes through 2 lenses.

Answer 20

compound microscope

Question 21

Provides a three-dimensional view of larger specimens at lower magnifications, typically used for dissection or examining the surface of objects.

Answer 21

Stereomicroscope/Dissecting microscope

Question 22

Provides detailed images of the internal structure of thinly sliced specimens by transmitting electrons through them. Can magnify up to 250,000x

Answer 22

TEM

Question 23

Produces detailed three -dimensional images of the surface of specimens by scanning them with a focused beam of electrons. Can magnify up to 100,000x

Answer 23

SEM

Question 24

Uses fluorescence and phosphorescence instead of, or in addition to, reflection and absorption to study properties of organic or inorganic substances. It’s often used in biological research to view specific components within cells.

Answer 24

fluorescence microscope

Question 25

increase of an object’s
apparent size

Answer 25

magnification

Question 26

power to show details clearly

Answer 26

resolution

Question 27

Both are needed to see a clear image

Answer 27

Magnification and resolution

Question 28

the visible area seen through the microscope when the specimen is in focus. The greater the magnification the smaller the view.

Answer 28

Field of view

Question 29

a specimen is in focus at the desired magnification when the image seen through the ocular lens is sharp and clear

Answer 29

focus

Question 30

area of field of view

Answer 30

A=π × r^2

Question 31

the ___ the magnification, the ___ the view

Answer 31

greater/lesser ; smaller/bigger
