Microscope Magnification and Field of View

The video tutorial explains how to measure objects using a microscope, focusing on the relationship between magnification and field of view. It introduces a formula to calculate changes in field of view when magnification changes. Practical examples and practice problems are provided to help understand the concept of estimating the size of organisms under different magnifications.

What happens to the field of view as you increase the magnification on a microscope?

• It increases.

• It decreases.

• It remains the same.

• It becomes clearer.

Which formula is used to calculate the change in magnification?

• Higher magnification multiplied by X equals lower magnification.

• Lower magnification divided by higher magnification.

• Higher magnification divided by lower magnification.

• Lower magnification multiplied by X equals higher magnification.

If the field of view at 100x is 1200 micrometers, what is it at 600x?

• 200 micrometers

• 600 micrometers

• 1200 micrometers

• 7200 micrometers

When decreasing magnification from 400x to 200x, what happens to the field of view?

• It decreases.

• It remains the same.

• It doubles.

• It halves.

What is the new field of view at 200x if it was 1000 micrometers at 400x?

• 2000 micrometers

• 500 micrometers

• 1000 micrometers

• 4000 micrometers

How do you convert millimeters to micrometers?

• Multiply by 100

• Divide by 100

• Divide by 1000

• Multiply by 1000

If the field of view at 200x is 1200 micrometers, what is the size of one cell if four cells fit across?

• 400 micrometers

• 300 micrometers

• 600 micrometers

• 150 micrometers

What is the field of view at 400x if it was 1200 micrometers at 200x?

• 2400 micrometers

• 1200 micrometers

• 300 micrometers

• 600 micrometers

What is the new field of view at 100x if it was 800 micrometers at 400x?

• 400 micrometers

• 3200 micrometers

• 1600 micrometers

• 800 micrometers

How does the field of view change when magnification decreases?

• It decreases.

• It remains the same.

• It becomes blurry.

• It increases.
