Microscopes: Magnification and Resolution

The video tutorial explains how magnification depends on the type of microscope used. It introduces the concept of magnification, providing an equation to calculate it. Two examples are given: one involving plant cells and another involving a virus, demonstrating how to calculate magnification. The tutorial also covers the concept of resolution, comparing images from electron and light microscopes, highlighting the differences in detail due to resolution.

What does the magnification of an image indicate?

• How many times smaller the image is compared to the object

• The actual size of the object

• The resolution of the image

• How many times bigger the image is compared to the object

In the first example, what is the magnification of the plant cell image?

• 100 times

• 10 times

• 50 times

• 200 times

What is the diameter of the virus in the second example?

• 5 times 10 to the power -6 meters

• 5 times 10 to the power -5 meters

• 5 times 10 to the power -3 meters

• 5 times 10 to the power -4 meters

What is the resolution of an image?

• The size of the image

• The minimum distance between two parts of the specimen that can be seen separately

• The magnification of the image

• The color depth of the image

Which type of microscope generally provides higher magnification and resolution?

• Simple microscope

• Compound microscope

• Electron microscope

• Light microscope
