Question

Compare the de Broglie wavelength of an alpha particle moving at 3.40E+7 miles per hour (1.52E+7 m/s) to that of a bullet moving at 700 miles per hour (313 m/s) and an electron with a speed of 1.30E+7 miles per hour (5.81 E+6 m/s). Which region of the electromagnetic spectrum are each of these wavelengths near? Ultraviolet 10-8 to 10-7 meters X-ray 10-11 to 10-8 meters Gamma ray 10-16 to 10-11 meters Smaller than 10-20 meters. Cannot detect wave-like properties. Only particle-like behavior will be observable.
