Light always travels at the speed of light but in a material it travels at the speed of light until it hits an atom. The energy from the photon is then absorbed and reemitted in the same direction which takes time.

WebOct 5, 2024 · The power of the light beam will be attenuated; the interaction of the unattenuated waves and the substance introduces a lag, which means there is a delay on the way through. That means that the speed of the wave will be measured as slower. It is the wavelength but not the frequency that changes. WebApr 10, 2024 · In this work, the radiation of a solitary polarization pulse that travels at the speed of light and has a variable or constant amplitude is discussed. It is shown that if the amplitude does not change, then such an object does not radiate outward, i.e., the field emitted by it remains completely localized inside the moving polarization pulse.
