A microscope operates under a wavelength of 400 nm with an NA of 1.6. Calculate the resolving power and discuss its implications for viewing plant cells.
💡 Hint: Use the formula and think about the typical size of plant cell structures.
You have two microscopes: one with a wavelength of 520 nm and an NA of 0.9; the other with 700 nm and an NA of 1.2. Determine which microscope has better resolving power and explain why.
💡 Hint: Don’t forget to use the formula for both and compare the results!
