De Broglie Wavelength

#### Q. Compare the de Broglie wavelength of a baseball moving at 90.0 miles per hour (40.2 m/s) to that of an electron moving at 1.30x10^7 miles per hour (5.81x10^6 m/s) and a proton with a speed of 1.30x10^7 miles per hour (5.81x10^6 m/s). Which region of the electromagnetic spectrum are each of these wavelengths near?
