6. what is this energy?
- electromagnetic radiation
- radiation
- electromagnetic energy
7. how is this energy related to energy levels?
- the emitted radiation is equal to the difference of 2 energy levels
- the emitted radiation is equal to a fixed quantum
- the emitted radiation is the difference between an energy jump
8. how is emission spectra shown on a spectrum?
- no lines at all
- coloured lines on a black background
- dark lines on a light background
9. what does the quantum energy do?
- corresponds to electromagnetic radiation of a specific frequency
- same frequency as radiation
- corresponds to electromagnetic radiation of a specific energy
10. what does each line represent in the balmer series?
- electrons returning to the second shell (n=2)
- electrons returning to third shell (n=3)
- electrons returning to infinity (n=∞)
11. what are the 3 series in the hydrogen spectrum?
- visible, ultra violet and infrared
- pashcen, balmer and lyman
- lyman, visible and infrared
12. how does light get removed in absorption spectrometer?
- light and photon have same frequency
- light and energy of a photon have the same frequency
- light and electron have same frequency
13. where do electrons return to in the lyman series?
- energy level n=1
- energy level n=2
- energy level n=4
14. How is absorption spectra shown on a spectrometer?
- no lines
- Dark lines against a bright background
- coloured lines on black background
15. what is the source of energy called that is released in emisson spectra?
- quantum energy
- packet of energy
- energy
16. what is the convergence limit?
- the point at which the atom has been quantised
- the point which the energy of an electron is no longer quantised, atom is ionised
- the point at which the atom is only ionised
