Light waves slow down as they enter the Earth's atmosphere from space.
Explanation:
When light waves pass through different mediums, such as moving from a vacuum (space) to a different medium (Earth's atmosphere), their behavior can change. The speed of light in a vacuum is constant and is approximately 299,792 kilometers per second. However, when light enters a different medium, such as Earth's atmosphere, it slows down. This happens due to the interaction of light with the particles in the medium.
In the case of Earth's atmosphere, light waves interact with the molecules and particles present in the air. As a result, they experience scattering, absorption, and re-emission processes. These interactions cause a delay in the propagation of light, which ultimately slows it down.
So, in summary, light waves slow down as they leave the vacuum of space and enter the Earth's atmosphere.
