Absorption spectra

When photons of light pass through a gas, the photons with the same energy as the energy gaps in the atoms can be absorbed. This causes an absorption spectra, as shown below.

A continuous spectrum of colour with thin black lines dividing it up into unequal parts.

Because the energy levels are the same, the lines in the emission spectra of an element are in the same position as the lines in the absorption spectra of the same element, as shown below.

Spectrum of colour, thin black lines dividing into unequal parts. Spectrum directly above it is black with thin coloured lines, all different colours, dividing it up into the exact same unequal parts.

Although sunlight appears to be a full continuous spectrum when viewed with a spectroscope, more detailed observation shows black narrow lines.

These 'Fraunhofer' lines are due to the absorption of light of specific frequencies by the gases in the upper atmosphere of the sun.

Question

Which of the following statements are true?

\(1\). Line spectra are produced when electrons move from one energy level within an atom to another energy level.

\(2\). The energy levels in the atom have definite values.

\(3\). Line spectra are produced when atoms lose electrons.
