23.1 Telescopes Review
Across
- 2. Short wave EM radiation that comes from very hot sources; allows us to see inside our bodies.
- 6. Type of EM radiation with waves longer than red light.
- 9. The distance that light travels in one year.
- 10. Radiation that travels as a wave; oscillations of electric and magnetic fields.
- 14. Device that separates light from a source into its individual wavelengths, telling us what the source is made of.
- 17. Hubble, Spitzer, Compton, Chandra; telescopes not limited by Earth's atmosphere,
- 20. telescope A type of telescope that uses both mirrors and lenses.
Down
- 1. _____ rays have the shortest wavelength and highest frequency.
- 3. The form of EM radiation that has the longest wavelength, and lowest frequency.
- 4. The distance between the peaks of an EM oscillation.
- 5. EM radiation with waves longer than visible light, used for cooking.
- 7. Telescopes that use a large dish antenna to detect faint radiation from distant objects in the universe.
- 8. A person who explores the universe beyond Earth.
- 11. A pattern fprmed by a group of stars; resembles a mythological figure.
- 12. The number of waves that pass a fixed point each second.
- 13. Telescope type first invented by Newton; use mirrors to gather light.
- 15. Telescope type first used by Galileo for astronomy; use lenses to gather light.
- 16. ROYGBIV
- 18. Objects in our solar system Greek for "wandering star".
- 19. Shortwave EM radiation just past the short end of the visible spectrum.
