Hi, just a basic question , what are the main methods of determining the structure of a solid in order to test its genuinety i.e. gold... if i were to be given a piece of gold, how would i check that it is genuine gold? could i use x ray diffraction (If so what measurements /tests would i...

assuming that Delta p = aprroxiamtely p, how can the uncertainty principle, be manipulated in order to achieve the speed of an alpha particle trapped in a nucleus of just say uranium 238 with proton number 92 ? or any other nucleus...what is the main manipulation steps of the formula?would...

thanks for that, but can the lattice constant be worked out from this information?and how can i use the bragg formula to ge this?

hi, I've been bashing my head against the wall for the past few days trying to work this one out! ive worked out a de broglie wavelength of electrons accelerated from rest by a voltage of 100v to be around (1.23 x 10 ^-10) m. now using a KCl diffraction , these electrons cause a first...
