What the angles among the direction are of travel of light the electric field and the associated magnetic field?
Answer:
The magnetic field created by a changing electric field is always at right angles to the electric field itself. The electric field formed by a changing magnetic field is always at right angles to the magnetic field itself.
Light Contains of electric and magnetic fields that vary in an oscillatory fashion in both time and space. The changing electric field generates the magnetic field. The magnetic field created is changing itself and its changing produces an electric field which itself is changing. Therefore the electric and magnetic fields of which light consists are always at right angles to each other.
In addition the direction in which light travels is the direction of the vector E*B. Since the definition of the cross product this direction is perpendicular to both E and B.
