Sb1a Microscopes

Question 1

Most common number of lens in microscopes today

Answer 1

2x lenses ( objective lens and eyepiece lens )

Question 2

Who used a microscope to discover cells

Answer 2

Robert Hooke in 1665

Question 3

Equation for magnification of a microscope

Answer 3

Objective lens x eyepiece lens

Question 4

What does the detail obtained by a microscope depend on

Answer 4

Detail obtained by a microscope also depends on its resolution

Question 5

Resolution definition

Answer 5

The smallest distance between two points that can still be seen as two points

Question 6

Electron vs light microscope differences

Answer 6

Electron microscope uses a beam of electron to formulate an imagine whereas light micro spices use light .
Electron microscopes have higher magnification and resolution however cannot be used to view living cells .

Question 7

Measurements of microscopes

Answer 7

Millimetres 10^(-3) - mm
Micrometers 10^(-6) - μm
Nanometers 10^(-9) - nm
Picometer 19^(-12) - pm

Question 8

Formula for magnification

Answer 8

M= i / A ( I = image / A = actual size of cell / M = magnification)
