Microtubules are protein filaments that are only 25 nm in diameter. This is smaller than the diffraction limit for visible light. Assume that you have microtubules labeled with rhodamine 6B dye.

(A) What color excitation and emission is rhodamine?

(B) How thick does the microtubule appear in the fluorescence microscope if the NA of the objective is 1.25?
