Unformatted text preview: 1. Solids are made of nuclei and electrons. Much of our information about solids is found by studying them According laws electron using other particles like = (photons) and neutrons. ticles, with to the E = of quantumwhere E light mechanics, all particles act like waves and waves act like par the relation h/ p, is the wavelength, p is the momentum, and h is Planck's constant. The relation of energy and neutron momentum for E= photon E= E= particles like electrons and neutrons is E p 2 / 2m , and for photons is E the energies in eV for each of the particles below for the wavelength shown: E= = 0.1 nm Particle pc .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
