Atomic spectra is a ______ spectra.
- A
Continuous
- B
Discrete
- C
Both options A and B
- D
None of these options are correct
OPTION A: Black body radiation is an example of continuous spectra.
OPTION B: When an atomic gas or vapor at much less than atmospheric pressure is suitably excited usually by passing an electric current through it, the emitted radiation has a spectrum, which contain certain specific wavelength only. Such a spectrum is called atomic spectra.
Atomic spectra is an example of discrete spectra or line spectra.
Hence, B is the correct option.
OPTION C: As only option B is correct. Hence, it is an incorrect option.
OPTION D: As only option B is correct. Hence it is an incorrect option
