Question

which of the three factors affecting image quality is altered by adjusting the intensity of the light source?
○ resolution
○ contrast
○ magnification

Explanation:

• Resolution refers to the ability to distinguish fine details, and adjusting light intensity doesn't directly affect it.
• Magnification is about how much larger the image is compared to the specimen, and light intensity adjustment doesn't change magnification.
• Contrast is the difference in brightness between the specimen and the background. Adjusting the light source's intensity can alter the brightness levels, thus affecting contrast (e.g., increasing light intensity can make the image brighter, changing the contrast between the specimen and background).

Answer:

Contrast
