Imagine that the light from a hot, dense object passed through a cool, low density cloud and then through a prism. If the temperature of the hot, dense object were increased slightly, which of the following changes would happen to the resulting spectrum?
a. the lines would move to the blue end of the spectrum
b. More lines would appear at the blue end of the spectrum
c. the lines would move toward the red end of the spectrum
d More lines would appear at the red end of the spectrum
e. the lines in the spectrum would not change.
Why???

Increasing the temperature of the source would increase the thickness or brightness of the lines a small amount, but would not shift them to the blue or the red end.
Shifting of the lines is due to the motion of the object towards us (blue shift) or away from us (red shift).

Hi. The answer from lindajune is correct. But the increase in temperature COULD cause new lines to become visible, but not shifted. I would think that new lines would tend to be bluer. Therefore I would say "B".

Color is not related to intensity,it is the result of wavelength.
That's it!

Maybe it's "D."
