Universe and Waves

2. A vast, glowing cloud of gas and dust in space, often where stars are born
5. A repeated back-and-forth or up-and-down motion.
8. The highest point on a transverse wave.
9. A huge, hot, celestial body composed of gas that emits its own light
11. The distance between two consecutive similar parts of a wave (e.g., crest to crest).
12. System- A star and the objects that orbit around it
14. The number of waves that pass a fixed point in a given amount of time, often measured in Hertz (Hz)
15. The maximum distance the particles of a medium move from their rest position; related to energy/intensity
16. A small, frozen mass of ice, dust, and rock that orbits the sun, creating a tail when heated

1. The fundamental force of attraction that pulls objects together in space
3. Everything that exists, including all space, matter, energy, and time
4. The curved, repeating path of a celestial body around a star or planet
6. A large, spherical body that orbits a star, such as Earth or Jupiter
7. A small, rocky, or metallic object orbiting the sunWave: A disturbance that transfers energy from one location to another
10. A massive collection of gas, dust, and billions of stars held together by gravity
13. The material through which a wave travels.
17. The lowest point on a transverse wave.
