    I Silly question on the relativity of simultaneity

    Something that I consider very silly, yet I try to solve relates to the relativity of simultaneity. According to SR , two evevnts taking place in different positions along the line of relative motion of two inertial observers are not simultaneous in both frames. Now, I wanted to see how this...

    Index of refraction vs frequency

    Hello! I have a question concerning the relation of the index of refraction of a material with E/M wave frequency. If we take the classical Feynmann approach, we can envision the material as a series of atoms, with electrons bound with springs to the nuclei. Let the natural frequencies of...
