The seeing ability or resolution of radiation is determined by its wavelength. If an atom is approximately 10-10 m in diameter, how fast must an electron travel to have a wavelength smaller than the size of an atom?

Question 2

If a rubidium surface is irradiated with blue light of wavelength 450.0 nm, what is the kinetic energy of the electrons emitted? (The work function for rubidium is f = 2.09 eV.)
