Energy levels Flashcards
1
Q
Explain the meaning of line spectra
A
Specific frequencies or wavelengths that give details about absorption
2
Q
Explain how line spectra provided evidence for the existence of energy leave in the atoms
A
Photons with particular energies produce different pattern in the line spectra
3
Q
Explain how atoms in a vapour emit light
A
When atoms energy they rise energy levels
When they drop energy levels they emit photons
4
Q
Explain what is meant by a spectral light
A
A line when split each wavelength is seen as a different line
5
Q
Explain why the atoms of different elements produce light of different colours
A
Different colours have different frequencies
Frequencies depends on different energy levels
Different atoms have different energy levels
