What are three properties of electromagnetic waves?
1. They travel slower than the speed of light, they include visible light waves, and they can transfer energy through empty space.
2. They need matter through which to travel, they travel at the speed of light, and they include visible light waves.
3. They travel at the speed of light, they include ultraviolet waves, and they can transfer energy through empty space.
4. They include ultraviolet waves, they need matter through which to travel, and they travel slower than the speed of light.

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
