an electromagnetic wave, such as a sound wave
a mechanical wave, such as an X-ray
a mechanical wave, such as a sound wave

Respuesta :

Electromagntic wave, such as an X-ray.

Explanation:

  • Electromagnetic wave does not require any medium to travel. These waves propagate outwards from the source.
  • They can travel even through the vacuum of outer space.
  • The major source is the sun which emits radiation in the form of the Electromagnetic spectrum.
  • These waves travel through oscillating electrical and magnetic fields generated by the oscillating charged particles.
  • These waves oscillate in the perpendicular direction of planes concerning each other and are in form.
  • Electromagnetic waves travel at speed of light.

Answer:a mechanical wave, such as an x-ray
