A consistent set of units that may be used in de Broglie’s Eq. 2-2.1 is: wavelength in cm, mass in g, velocity in cm s-1 , and h (Planck’s constant) in cm2 s-1 (or erg s). What is the wavelength in cm and in angstroms of (a) an electron travelling at 106 cm s-1, a velocity typical in the electron microscope? (b) a baseball or cricket ball thrown at 103 cm s-1 ? Assume that mass equals 2.00 x 102 g.
