Radio waves and visible light both travel through space, but their range and behavior can vary.
Radio waves have a longer wavelength than visible light, which allows them to travel great distances in space. They can travel through the vacuum of space without being significantly attenuated. The exact range of radio waves depends on various factors such as the frequency and power of the signal, interference, and the sensitivity of the receiving equipment. However, under ideal conditions, radio waves can travel vast distances in space, potentially reaching across galaxies.
Visible light, on the other hand, behaves differently from radio waves. It is a form of electromagnetic radiation with shorter wavelengths. While visible light can also travel through space, its range is limited compared to radio waves. Visible light can travel through the vacuum of space, but it can be affected by scattering and absorption by interstellar dust and gas. This can cause a decrease in the intensity of light over long distances.
In summary, radio waves can travel much farther in space compared to visible light. While radio waves can potentially travel across vast cosmic distances, visible light is more susceptible to scattering and absorption, which limits its range.
