B. They travel with the speed of light
C. They are longitudinal
D. The electric and magnetic fields are at right angles to each other

Correct Answer:

Option C – They are longitudinal


All electromagnetic waves are:

  • transverse waves; can travel through a vacuum ;
  • travel at exactly the same speed in a vacuum, the speed of light, 300,000,000 m/s.
  • transfer energy from one place to another;
  • can be reflected;
  • can be refracted.
  • The oscillations of and are perpendicular to each other and are in the same phase.
