Question

a) If you wanted to use visible light to image something, what is a reasonable estimate for your resolution?

b) What is the frequency that corresponds to this wavelength? The human visual system has a “frame rate” on the order of 100 Hz. Does it make sense that we perceive the intensity of emitted by a laser as constant in time?

c) Suppose you wanted to detect details around the size of an atom (10^-10 m). What frequency and type of electromagnetic radiation does this correspond to? (This is the exact principle used in X-ray crystallography which is used to characterize the physical structures of molecules and X-ray diffraction, used to measure the crystal lattice structure of solids.)
