Microscopes and Magnification

Question 1

What is an estimate?

Answer 1

An educated guess

Question 2

Why do we use estimates?

Answer 2

Save time

Question 3

What is magnification?

Answer 3

The process of enlarging the physical appearance/image of something

Question 4

How do you find magnification? (formula)

Answer 4

M = I/A
(Magnification = image size/ actual size)

Question 5

How do you find the image size? (formula)

Answer 5

I = A X M

Image size = Actual size x Magnification

Question 6

How do you find the actual size? (formula)

Answer 6

A = I/M

Actual size = Image size/Magnification

Question 7

What is the resolution?

Answer 7

The ability to distinguish between two points as separate structures

Question 8

What happens if you have a low resolution?

Answer 8

The image is blurry

Question 9

What happens if you have a high resolution?

Answer 9

The image is clear

Easy to see

Question 10

When was the electron microscope invented?

Answer 10

1930’s

Question 11

What does an electron microscope use?

Answer 11

It uses beams of electrons

Passes through through a specimen to build up an image

Question 12

What is the maximum magnification of an electron microscope?

Answer 12

x2000000

Question 13

What is the minimum magnification of an electron microscope?

Answer 13

x0.0000002

Question 14
