Challenge Problems
Push your limits with advanced challenges
A microscope has a numerical aperture of 1.25 and is used with oil immersion. If the light path is altered to increase the angle of light entering the lens, how would this affect the resolution?
💡 Hint: Consider the formula for NA and how each component influences microscopy.
You are observing a living cell using phase contrast microscopy. Describe the impact of using this technique compared to bright-field microscopy on your ability to see fine details.
💡 Hint: Reflect on how staining affects sample visibility.
