A microscope has an ocular magnification of 10 and a high power objective magnification of 40. What is the highest total magnification of the microscope?

• 500x

• 400x

• 50x

• 40x

Answer explanation

To find the total magnification, multiply the ocular magnification (10) by the objective magnification (40). Thus, 10 x 40 = 400. Therefore, the highest total magnification of the microscope is 400x.

What happens to your field of view as you increase magnification?

• it increases

• it decreases

• it stays the same

• it disappears

Answer explanation

As you increase magnification, your field of view decreases. This is because higher magnification focuses on a smaller area, allowing you to see more detail but less of the overall scene.

A letter "e" has been placed on the slide in the proper orientation. How does it appear on the slide when you look through the microscope?
