    Undergrad Understanding Light: Puzzled by Velocity?

    Puzzled by light? Why has light same velocity when measured from any frame? I know about Maxwell's theoretical deduction (but not clearly) and the Michelson-Morley experimental deduction. When understanding light I tried to make it analogous with sound. It just further degraded the...

    Graduate Got wrong from right equations

    I got this problem while I was combining relativistic equations: For particle which is in motion, v = l /t or, l = v * t or, l= v * t0/(1-v^2/c^2)^(1/2) ' Relativistic equation for time "t" If the particle was light, l =(c * t0)/(1-v^2/c^2)^(1/2) '...
