Object faster or just as fast as light

Although you can't change the speed of light, you can change the wavelength if the light is first absorbed by a substance's electrons then put them into an excited energy state. When the electrons return to their normal ground state they will emit light of the particular wavelength corresponding to hte energy difference between the two states.
