Chemistry - Electromagnetic spectrum

Chemistry - Electromagnetic spectrum

1. spectrum extends from high frequency

   • gamma waves
   • to low frequency
     • radio waves

2. Visible light is part of the electromagnetic, the only part of the spectrum that the human eye can see

3. consists of 7 primary colours

   • red to violet

4. Waves are described in terms of their frequency, amplitude and wavelength

   • wavelength - distance between two peaks or troughs in a wave
   • amplitude - peak movement from its rest point
   • frequency - number of waves passing in one second
