red light waves have wavelength, frequency, and travel at the speed compared to blue light waves when both are in space.

Explanation:

In a vacuum (space), all electromagnetic - waves including red and blue light travel at the speed of light. The wavelength and frequency of light are related by the formula $c = \lambda f$ (where $c$ is the speed of light, $\lambda$ is wavelength, and $f$ is frequency). Red light has a longer wavelength than blue light. Since $c$ is constant, a longer wavelength corresponds to a lower frequency.

Answer:

longer, lower, same
