1 answer

To classify each wave as either electromagnetic or mechanical:

  • W (the Sun, light): Electromagnetic
  • X (a dog, sound): Mechanical
  • Y (the ocean, motion): Mechanical
  • Z (a battery, electrical): Electromagnetic

So the classifications are:

  • W: Electromagnetic
  • X: Mechanical
  • Y: Mechanical
  • Z: Electromagnetic
