Relativity has fascinated many young minds (old too).
Below is a conversation between a student and a Physics Teacher on Facebook chat.
IF A TRAIN TRAVELS WITH SPEED OF LIGHT; WHAT HAPPENS TO ITS LENGTH?
Please refer to ther following links for more information on the question.
I wanted to to know that why the attraction of electrons towards the positive plate of the the CRT is not taken into account in the Einstein’s explanation of the photoelectric effect and only the velocity imparted by the striking photon is considered.
I request you to kindly read the story well. Every aspect is dealt in detail. Please go thoroughly through the text material or the link to photoelectric effect provided in this page.
If the definition of the speed of light is for massless particles, then how is a proton, having mass, accelerated to the speed of light? This sounds like a conumdrum.
No massive particle has not so far crossed the speed of light. Even the extremely light particles – the neutrinos – couldnot cross the speed of light. Protons have not crossed the speed of light. When it nears the speed of light, the relativistic mechanics will become prominent and the it is to be treated is different from the classical mechanics.
if the papers of Einstein depend upon speed of light as its base, and the particles which have speed greater than the light could pose treat to be it. then in that case why cant that particle could be set as the Einsteins theorms base so that it doesnt violate and simple corrections could correct the theorms!!
