## Magnification Answers

## 1. What is the equation for magnification?

## Image = Actual size x Magnification

##

## 2. The size of an image through an electron microscope is 25mm and the magnification is x100,000. Calculate the actual size of the object

## 0.00025mm

##

## 3. Rearrange the magnification to make Actual size (A) the subject

## Actual size = Image / Magnification

##

## 4. Which microscope has a higher magnification

## A - Electron microscope

##

## 5. What is the total magnification of a light microscope with an eyepiece lens of x10 and an objective lens of x30?

## 300x

##

## 6. What is the total magnification of a light microscope with an eyepiece lens of x2 and an objective lens of x15?

## 30x

##

## 7. A drawing of a cell is 2 cm and the scale states that it is 0.2 mm in real life, what is its magnification?

## Magnification = image size / actual size

## Magnification = 2 / 0.2 = 10x

##

## 8. Roughly, what is the maximum magnification that a light microscope can achieve?

## ~1500x

##

## 9. Roughly, what is the maximum magnification that an electron microscope can achieve?

## ~1,000,000x

##

## 10. An image seen through a light microscope is 25mm and the magnification is x200. Calculate the actual size of the object

## 0.125mm
