The radiation curve is a plot of light intensity versus frequency for an incandescent source. If this light is first passed through a cool gas, the resulting radiation curve would most probable look like

1) I.
2) II.
3) III.

This best illustrates that the atoms of gas have
4) been excited.
5) absorbed part of the light.
6) simplified selective frequencies of the transmitted light.

Question 2

The radiation curve is a plot of light intensity versus frequency for an incandescent source such as a glowing lamp filament. If the source of light were excited atoms in the gaseous phase, the radiation curve would look like

1) I.
2) II.
3) III.
4) IV.

The plot shown in IV is of
5) monochromatic light.
6) a very bright source.
7) light that has passed through a thin slit.
