A sheet of aluminum 1 mm thick reduces the intensity of a monochromatic x ray beam to 23.9% of at original value. what is the wave length of xray.
When working in the grand canonical ensemble we write the grand potential as $\Omega = \Omega (T,V,\mu)$. In this case we are taking the chemical potential $\mu$ to be an independent variable. This ...
I was rereading Purcell's Electricity and Magnetism as research for another question, and I found this passage: In metals Ohm's law is obeyed exceedingly accurately up to current densities far ...
Many experiments, such as optical, superconductivity, etc, use the samples that involve rare earth metals and transition metals. Why are they used that often. Is the main reasons: They have the ...
