​ Eyepiece ( ​ (a)   ) × Objective lens ( 40X ) = Total Magnification ( 400X )

• 10X
• 4X
• 40X
• 100X

Total Magnification is

• Objective lens X Eyepiece lens

• Eyepiece lens X Eyepiece lens

• Eyepiece lens X Total Magnification.

Compound Microscope because

• Uses two different lenses

• Uses one lens

Light source can be a bulb or a mirror
