  • Light is a form of electromagnetic radiation, in the range of wavelength corresponding to the visible region of the electromagnetic spectrum
  • The Speed of light = Frequency X Wavelength
  • Energy = Planck's constant X Frequency
  • Therefore Frequency is directly proportional to Energy
  • Freq is inversely proportional to Wavelength 
  • The lower the wavelength, the higher the frequency and the greater the energy

Absorption spectra:
When light shines through gaseous atoms, photons of certain energy may be absorbed by an atom causing an electron to move from a lower energy level to
