The Universe and Waves

4. What the sun will be in its final stages of life
5. A type of galaxy that is old and can no longer produce stars
7. The same type of galaxy as the milky way
11. a graph of many stars visualizing the relationship between luminosity(Brightness) and the stars temperature
12. the distance between two waves from their highest or lowest points
14. How bright a star appears to be from Earth
15. The range of electromagnetic waves organized from their wavelength or freauency
18. the theory that indicates our universe is expanding
19. Planets that orbit nearest the sun

1. The waves with the shortest wavelength on the spectrum
2. The number of waves produced in a specific amount of time
3. The substance that a wave might travel through
6. A type of matter that does not emit electromagnetic energy
8. Galaxies that do not have a uniform shape
9. The lowest area of a wave
10. The height of a wave measured from the rest, or bottom of the wave, to the top
11. A unit used to measure a frequency for a wave
13. An example from this specific type of wave is Doppler radar
16. The top of a wave
17. Waves The type of electromagnetic waves with the least amount of energy
