Homework Statement Calculate the difference in time after one year between a clock at Earth's surface and a clock on a satellite orbiting at 300 km above the surface Homework Equations T = T0 / (1 - 2gR/c^2)^.5 That is, this...

OK, doing this, I get a speed of 0.29C for the velocity of the spring--i.e., much faster than what could ever be realistically achieved. What am I missing here? There has to be something. A monochromatic laser going back and forth, how is it capable of reaching such a wide range of...

Homework Statement A laser of frequency f0 is connected to a spring which oscillates in one dimension with a period T and amplitude A. The laser excites the 1st four Paschen series lines of hydrogen. What is f0 Homework Equations I'm assuming that I'll need the Doppler shift equations, f =...

Hi, I'm trying to get a geometric idea of what the derivative of a velocity vector is. For example if you're talking about the space between vx and vx + dvx, where vx is a velocity along the x axis. Would it be like an infinitesimal sphere around the end of the vector? Thanks... (Added...
