Question

Compare the de Broglie wavelength of an alpha particle moving at 3.40x107 miles per hour (1.52x107m/s) to that of a baseball moving at 90.0 miles per hour (40.2 m/s) and a proton with a speed of 1.30x107 miles per hour (5.81x10 m/s). Louis de Broglie Which region of the electromagnetic spectrum are each of these wavelengths near? A. Ultraviolet 10-8 to 10-7 meters B. X-ray 10-11 to 10-8 meters Gamma 10-16 to 10-11 meters ray Smaller than 10-20 meters. Cannot detect wave-like properties. Only particle-like behavior will be observable. Wavelength Particle Mass (kg) Velocity (m/s) Region (m ) Hill alpha particle 6.64x10-27 1.52x107 baseball 0.140 40.2 proton 1.67x10-27 5.81x106
