| 41. | It was also planned that the telescope would be used for spectral line work at millimeter wavelengths.
|
| 42. | The spectral lines of carbon monoxide reveal that the gas is dense, and warm and fairly opaque.
|
| 43. | Curiously, very defined spectral lines appeared.
|
| 44. | This piece of plasma will then emit strongly at the spectral lines and weakly between the spectral lines.
|
| 45. | Beyond this level, spectral lines merge.
|
| 46. | This piece of plasma will then emit strongly at the spectral lines and weakly between the spectral lines.
|
| 47. | These observed spectral lines are due to the electron making transitions between two energy levels in the atom.
|
| 48. | Type IIn supernovae are characterised by additional narrow spectral lines produced in a dense shell of circumstellar material.
|
| 49. | This gives a stronger spectral line.
|
| 50. | The spectral lines involved are broadened.
