that still doesnt answer it. what i mean is...pretend i have a spring coil. & i keep stretching it. and time how long it takes for one wave pulse to travel from one end to the other. and use the formula v=d/t when u do that, you get velocity. velocity usually increases. i need an internet source that states that. & is there a theory that says that
