Waves, sound and light

Physics

After this lesson, you should be able to:

  • Describe the source of a wave as an accelerating charge
  • Describe with the use of a diagram how an electromagnetic wave consists of electric and magnetic fields oscillating at right angles to each other and mutually generating one another
  • State that these mutually regenerating fields propagate through space at a constant speed, the speed of light, represented by c.
  • List the main types of electromagnetic radiation and arrange them in order of increasing frequency or wavelength.
  • Calculate the frequency of an electromagnetic wave given its wavelength and vice-versa using c = f \(\lambda\)
  • Give examples of uses of the different types of electromagnetic radiation
  • Discuss possible dangers associated with different types of radiation
  • Define a photon and calculate its energy using E = h f = h c / \(\lambda\)
