1. |
Hot opaque solid (dense gas) emits light of all
|
|
|
wavelengths continuous spectrum of radiation
|
|
2. |
Low density (transparent) hot gas emits
|
|
|
spectrum of bright emission lines
|
|
|
3. |
Low density (transparent) cool gas in front of a
|
|
|
blackbody absorbs wavelengths from the

|
|
continuous spectrum dark absorption line
|
|
|
spectrum on continuous spectrum (wavelengths
