  1. They are at right angles ✔
  2. They are parallel
  3. They travel at different speeds

Why: A radio wave has an electric field and a magnetic field. The two are perpendicular, 90 degrees apart, as the wave moves along.

Huh, didn't know that: Both fields are also at right angles to the direction the wave travels.

The dad joke
Electric and magnetic fields make a great team. They're right angle for each other.
