Is the solar wind the light that reaches Earth?
No, the light from the Sun is thermal radiation, which is electromagnetic waves. The light travels at , the speed of light in vacuum. The solar wind is something completely different: it’s the high energy particles that get blown off the surface of the Sun by magnetic activity. The solar wind is made of charged matter particles, like protons and electrons. It travels much more slowly than light.
