1.
An emission line spectrum is produced by
a hot solid
a hot low-pressure gas
a cold solid
a cool gas in front of a lamp
2.
A photon is emitted when an electron moves from an energy level of −1.5 eV to −3.4 eV. The photon energy is
4.9 eV
−1.9 eV
2.55 eV
1.9 eV
3.
The wavelength of the photon of energy 2.0 eV is about (hc = 1240 eV nm)
620 nm
62 nm
2480 nm
310 nm
4.
Dark lines in the spectrum of sunlight arise because
the Sun is cooler at those wavelengths
cooler gases absorb specific wavelengths
light is refracted
the gases emit those wavelengths
5.
The energy levels in an atom are discrete. This is evidenced by
continuous spectra
beta decay
line spectra
the photoelectric effect only
6.
An atom has 5 energy levels. The maximum number of different photon energies it can emit is
