Question

which objective lens give you the largest field of view?

4x
10x
40x
100x

Explanation:

🆕 New Concept Discovered: Microscope Field of View
Inverse relationship between magnification and visible area

Step 1: Understand Field of View (FOV)

The field of view (FOV) is the total visible area you can see when looking through the microscope eyepiece. Think of it like zooming in with a camera:

• When you zoom out (low magnification), you see a wide, broad area.
• When you zoom in close (high magnification), you see a very small, detailed area.

Step 2: Relate Magnification to FOV

There is an inverse relationship between magnification and the field of view:

• Lower magnification \(

ightarrow\) Larger field of view (you see more of the overall specimen).

• Higher magnification \(

ightarrow\) Smaller field of view (you see a tiny, highly detailed section of the specimen).

Step 3: Compare the Options

We want the largest field of view, which corresponds to the lowest magnification power:

• \(4\text{X}\) (Lowest magnification)
• \(10\text{X}\)
• \(40\text{X}\)
• \(100\text{X}\) (Highest magnification)

Therefore, the \(4\text{X}\) objective lens provides the widest, largest field of view.

Answer:

4X
