Find the kinetic energy of the following particles that each have a de Broglie wavelength of 0.50 nm.?
(a) photons
____eV = 2480eV
(b) electrons
____eV
(c) neutrons
____eV
(d) α particles
____eV
i know E= hc/wavelength which = a and after that I am stuck i know that the wavelength =...
A photon having 20 keV scatters from a free electron at rest. What is the maximum energy that the electron can obtain?
