MCQ
From which source a continuous emission spectrum and a line absorption spectrum are simultaneously obtained
- ABunsen burner flame
- ✓The sun
- CTube light
- DHot filament of an electric bulb
✓
Answer
Correct option: B.
The sun
b
From the Bunsen burner flame, there are certain order of elements which causes absorption and hence causes the absorption and emission spectrum to be discontinuous.
From the Bunsen burner flame, there are certain order of elements which causes absorption and hence causes the absorption and emission spectrum to be discontinuous.
Tube light gives us photons due to excitement of electrons present inside the tube. This gives us a continuous emission spectrum but doesn't give us any absorption spectrum.
The hot filament of a bulb gives us a spectrum due to the excitement of electrons around the filament due to the high energy released by it. This too gives us a continuous emission spectrum but no absorption spectrum. Sun emits white light which causes a continuous emission spectrum. The elements present in the causing the sunlight gives us a line absorption spectrum.
