Mid- Term Review

  • elliptical orbits- to calculate, eccentricty= distance between foci/length of major axis
  • transverse wave- particles move perpendicular to the direction of travel
  • compressional wave- particles move parallel to the direction of travel
  • refraction- the bending of light as it moves from one substance to another
  • diffraction- the bending of a wave around an object
  • EM waves- have an electric and magnetic field
  • distance- how far the route is you take to get some somewhere
  • displacement- how far one travels as "the crow flies"
