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
