Question

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

resolution
magnification
contrast

Explanation:

Identify the factors of microscopy image quality

The three primary factors affecting image quality in microscopy are magnification, resolution, and contrast.

Analyze the effect of light intensity

Adjusting the intensity of the light source directly changes the brightness difference between the specimen and the background, which alters the contrast of the image.

Evaluate the remaining options

Magnification is determined by the lenses (objective and ocular), and resolution is determined by the wavelength of light and the numerical aperture of the lenses, neither of which is altered by changing light intensity.

Answer:

• Resolution
• Magnification
• Contrast (Correct answer)
