Using the de Broglie and Planck-Einstein formulas, and considering (A) a helium atom with a kinetic energy of 0.0025eV (i.e, thermal energy at 300K) and (B) a baseball (mass=500g) moving at 49m/s, evaluate and interpret the wavelength and frequency associated with the wave motion of each. How do these results compare with the size an atom (1Å) and the diameter of a nucleus (1x10-5)
