OZ2

• Speed of light = wavelength x frequency
• Energy of photon = Planck's constant x frequency
• EM spectrum:

  A) Visible

  B) UV

  C) Temporary reddening

  D) Quick tanning

  E) Tanning and sunburn

  F) Frequency

  
• What happens when radiation interacts with matter:

  A) Electronic energy

  B) Vibrational energy

  C) Rotational energy

  D) Translational energy

  E) Increasing energy

  
• When the change occurring to the matter is rotational, microwave radiation has been absorbed
• When the change is vibrational energy, IR radiation is absorbed
• If electronic energy change has occurred, visible or UV radiation has been absorbed
• What happens when UV radiation is absorbed:

  A) Ionisation

  B) Dissociation

  C) Release of energy ( Cl2 returns to original state)
