MCQ
The spectrum of light emitted by a glowing solid is
- ✓Continuous spectrum
- BLine spectrum
- CBand spectrum
- DAbsorption spectrum
✓
Answer
Correct option: A.
Continuous spectrum
a
Continuous spectrum arise from dense gases or solid objects which radiate heat. They emit radiation over a broad range of wavelengths, so the spectrum appear as smooth and continuous. Blackbody is a perfect example for emitting Continuous Spectrum. Any body which glows by radiating heat like incandescent light bulbs, electric cooking stove burners, flames etc emit radiation in Continuous Spectrum.
