Experimentation
Draw conclusion

Question 6

3 main parts of the microscope

Answer 6

Mechanical
Optical
Illuminating

Question 7

Define the parts whether it is Mechanical, Optical, or Illuminating

Arm
Base
Eyepiece
Condenser

Diaphragm
Revolving nosepiece

Answer 7

Arm = Mechanical
Base = Mechanical
Eyepiece = Optical
Condenser = Illuminating
Mirror = Illuminating
Coarse adjustment = Mechanical
Objective lenses = Optical
Diaphragm = Illuminating
Revolving nosepiece = Mechanincal
