Microscopes and Magnification

Question 1

What magnification is a light microscope?

Answer 1

X2000

Question 2

What magnification is that of an electron microscope?

Answer 2

X10 million far more detailed than a light microscope

Question 3

What are the steps for calculating magnification?

Answer 3

! Measure image in mm
! X by 1000 to get measurements in micrometers
! X by scale bar number

Question 4

What is the equation for magnification?

Answer 4

Magnification= Image size / real size

Question 5

Scale bar 1 micrometer = 20mm
20x1000= 20000 micrometers -image size
Real size = 1 micrometer (from diagram)
I/r= 20000/1
= x20000
