  • What do they all have in common? 700 - 420 nm 10 100 nm 1 0.01 nm 10-12 - 10-14 m 10-4 - 10-6 m 10-2 - 10-3 m 10-1 - 103 m

  • What do they all have in common?They can travel in a vacuumThey travel at 3 x 108m.s-1 in a vacuum (the speed of light)They are transverseThey are electromagnetic waves (electric and magnetic fields at right angles to each oscillating perpendicularly to the direction of energy transfer)

  • Mini-book

  • Mini-bookOne type of EM wave for each pageEach page should contain the wavelength and frequenciesEach page should contain uses and other interesting information (including dangers)Attractive to look at (and funny?)Homework due Friday 29th January

  • Mini-bookFinish for homework.Due Friday 29th January
