FIRST ANSWER IS THE CORRECT ANSWER Sect. 5.2 1. A continuous spectrum is one in which the intensity 2. (1) varies gradually from one wavelength to the next, without any sudden jumps 3. (2) is highest at a relatively few wavelengths and very low everywhere else 4. (3) is constant with time and does not fluctuate 5. (4) NVA 6. (5) NVA 7. 8. 9. 10. The absorption-line or dark-line type of spectrum is the one in which the 11. intensity 12. (1) changes very gradually with wavelength except for certain wavelengths where 13. it abruptly drops and then returns to its previous level 14. (2) changes very gradually with wavelength 15. (3) is very low except for certain wavelengths where it abruptly rises and then 16. returns to its previous level 17. (4) NVA 18. (5) NVA 19. 20. 21. 22. The kind of spectrum that has most of the light concentrated at a relatively 23. few wavelengths is called 24. (1) emission-line

(1) a cool, thin (low-density) gas in front of a continuous-spectrum source 34. (2) a thin (low-density) gas 35. (3) a glowing solid, liquid, or thick (high-density) gas 36. (4) NVA 37. (5) NVA 38. 39. 40. 41. When one has a continuous-spectrum source behind a cloud of cooler gas, that 42. source's spectrum will be of which type? 43. (1) absorption-line (dark-line) 44. (2) emission-line (bright-line) 45. (3) continuous 46. (4) NVA 47. (5) NVA 48. 49. 50. 51. The type of source having an emission-line spectrum is 52. (1) a hot, thin (low-density) gas 53. (2) a cool, thin (low-density) gas in front of a continuous-spectrum source 54. (3) a glowing solid, liquid, or thick (high-density) gas...
