Equations for sinusoidal electromagnetic radiation

Which of the following are true for sinusoidal radiation?
1) The electric field and the magnetic field have the same magnitude at the same point in space.
2) The electric field is perpendicular to the magnetic field.
3) The source of the radiation is oscillating charges.
4) The radiation pattern does not change with distance.
5) Oscillating charges are not accelerating.
6) The radiation travels perpendicular to the electric field.
7) The radiation travels perpendicular to the magnetic field.
8) The propagation direction of the radiation can be determined from the right hand rule.
9) The radiation pattern does not change with time.

Hi, I am having trouble with this problem. I have selected 1, 2, 3, 7, 8, however, it is marked as incorrect and would appreciate some guidance.

I have realized my mistakes. The radiation propagates perpendicular to both the electric AND magnetic fields. Also, since E = vB, electric and magnetic fields do not have the same magnitude.
