Doris observed that 8 Smallus Bugus' fit across the field of view, which was calculated to be 1,600 µm.  What is the size of one Smallus Bugus?

• 8 µm
• 1,600 µm
• 200 µm
• 12,800 µm

The ________ of the microscope would show you the SMALLEST field of view.

• low power objective
• medium power objective
• high power objective
• ocular

Bob calculated the field of view with an ocular of 10x and an objective of 10x to be 2,000 µm.  What would the estimated size of Green Goblin bacteria be when the objective was at 100x?

• 200 µm
• 50 µm
• 100 µm
• 1,000 µm

Here are the settings on a microscope:
Ocular Lens: 10x
Low Power Objective Lens: 4x
Medium Power Objective Lens: 20x
This image shows the field of view under low power (in millimeters).  
Calculate the field of view that would appear on medium power.  

• 800 µm
• 600 µm
• 900 µm
• 400 µm

Here are the settings on a microscope:
Ocular Lens: 10x
Low Power Objective Lens: 4x
High Power Objective Lens: 40x
Low Power Field Of View: 3,000 µm
Use this information to figure out how long this bacteria is on high power. 

• 300 µm
• 150 µm
• 100 µm
• 400 µm

A biologist sees this under a microscope at 10x ocular, and 40x objective.  What would the field of view be at 100x objective?

• 800 µm
• 2,000 µm
• 400 µm
• 1,000 µm
