### When something is enlarged.

2

## What is the definition of resolution?

### The ability to distinguish between 2 objects clearly. A higher resolution means the image is clearer.

3

## What is the formula to find the magnification?

### Image Size divided by Real Size.

4

## What is the formula to find the Image size?

### Magnification times the Real Size.

5

## What is the formula for finding the Real Size?

### Image size divided by the Magnification.

6

## What is the formula to find the Total Magnification?

### Eyepiece Lens Magnification time the Objective Lens Magnification.

###
mm

X 10 to the power of minus 3

8

## What are the units for Micrometers and how do you write it in standard form?

###

X 10 to the power of minus 6

9

## What are the units for Nanometres and how do you write it in standard form?

###
nm

X 10 to the power of minus 9

10

## What are the units for Picometers and how do you write it in standard form?

###
pm

11

## When were Light Microscopes invented?

### In the 1590s.

12

## How do Light Microscopes work?

### They work by passing light through the specimen. They let us see things like nuclei and chloroplasts and we can also use them to study living cells.

13

## When were Electron Microscopes invented?

### In the 1930s.
