What is the de Broglie wavelength (in meters) of a neutron traveling at a speed of 0.92 c? Since the neutron's speed is close to the speed of light (c), Special Relativity must be used when calculating the linear momentum (p). The mass of the neutron is 1.675 x 10-27 kg. Suppose that an alpha particle (mαα = 6.646 x 10-27 kg) has a kinetic energy of 75 keV. What is the alpha particle's speed (v) (in terms of "c")?...
(a) Rank the following particles in order of their de Broglie wavelength, from longest wavelength to shortest wavelength. If any two particles have the same de Broglie wavelength, state this. Explain how you made your ranking.

A photon of red light (wavelength = 730 nm) and a Ping-Pong ball (mass = 2.30 × 10 − 3 kg) have the same momentum. At what speed is the ball moving?
In Einstein's photoelectric experiment, the kinetic energy (K.E.) of an electron displaced from a metal by a photon was the difference between the energy of a photon and a threshold energy value for the metal. If you were to perform a similar experiment with lead, which has a threshold energy of 6.81 × 10⁻¹⁹ J, and ultraviolet light of wavelength 38.5 nm, what would be the speed (v) of the dislodged electron? (K.E. = 1/2mv². The mass of the electron...
