Calculate the de Broglie wavelength of: a) a mass of 100 kg moving at 1 meter per second, b) a free electron having a kinetic energy of 200 eV, and c) a free proton having a kinetic energy of 200 eV.
A) If the De Broglie wavelength of an electron is equal to 350 nm calculate the velocity of the electron. Assume that the electron's speed is non-relativistic. B) If the kinetic energy of an electron is 440 eV, calculate its De Broglie wavelength. For this non-relativistic electron you must first calculate its velocity from the general kinetic energy equation. Then you can find the De Broglie wavelength of the electron.
If the De Broglie wavelength of an electron is equal to 400 nm calculate the velocity of the electron. Assume that the electron's speed is non-relativistic. Answer: 1832.42 m/s If the kinetic energy of an electron is 400 eV, calculate its De Broglie wavelength. For this non-relativistic electron you must first calculate its velocity from the general kinetic energy equation. Then you can find the De Broglie wavelength of the electron. I cannot figure out the second part, please explain!

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")?...
