The "seeing" ability or resolution of radiation is determined by its wavelength. If the size of an atom is approximately 10-10 m, how fast must an electron travel to have a wavelength smaller than that of an atom? (me = 9.11 × 10^-31 kg and h = 6.63 × 10^-34 J×s)
a. 1.0 × 10^6 m/s
c. 5.4 × 10^5 m/s
b. 7.3 × 10^6 m/s
d. 3.4 × 10^6 m/s
