  • a)
    the wave intensity remains constant for a plane wave
  • b)
    total intensity of the spherical wave over the spherical surface centered at the source remains constant at all times
  • c)
    the wave intensity decreases as the inverse of the square of the distance from the source for a spherical wave
  • d)
    the wave intensity decreases as the inverse of the distance from the source for a spherical wave
