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")?...

The de Broglie wavelength of a particle depends only on the particle's charge the particle's energy O the particle's speed the particle's momentum. the particle's mass. The wavelength of some green light is 530.0 nm. What is the frequency of this green light? A certain shade of blue has a frequency of 7.13 x 10" Hx. What is the energy of exactly one photon of this light?

When a high energy photon passes near a heavy nucleus, a process known as pair production can occur. As a result, an electron and a positron (the electron\'s antiparticle) are produced. In one such occurence, a researcher notes that the electron and positron fly off in opposite directions after being produced, each traveling at speed 0.677c. The researcher records the time that it takes for the electron to travel from one position to another within his detector as 22.1 ns....

A spacecraft passes you traveling forward at 0.359 the speed of light. By what factor would its relativistic momentum increase if its speed doubled?
When a fast electron (i.e., one moving at a relativistic speed) passes by a heavy atom,...
When a fast electron (i.e., one moving at a relativistic speed) passes by a heavy atom, it interacts with the atom's electric field. As a result, the electron's kinetic energy is reduced, the electron slows down in the meantime, a photon of light is emitted. The kinetic energy lost by the electron equals the energy E_r of a photon of radiated light. E = K - K', where K and K' are the kinetic energies of the electron before and...
