In the limit of large distances, the electric field that is associated with the radiation magnetic fields is given by the real part of:

E(r)=[(μ(subscript 0) I(subscript 0) δ l)/(4pi)] cos θ ((-i ω)/r)exp [i(kr-ωt)]θ-hat

The magnetic field is given by the real part of:

B(r)=[(μ(subscript 0) I(subscript 0) δ l)/(4pi)] sinθ [((-i ω)/(rc))+(1/(r^2))]exp [i(kr-ωt)] phi-hat

Write down a list of up to nine features of the radiation fields that can be deduced from the form of the expressions for the radiationBandEfields. You should consider the relationship betweenEandB, the factors determining the amplitude of the wave, the polarisation of the wave, the speed of the wave and the shape of the waveform.

3. The attempt at a solution

E and B are perpendicular to each other.

They are travelling in the same direction.

They both have a sinusoidal shape.

They have different amplitudes.

They are linearly polarised.

That's all I can think of. Please help me think of some more.

How do I deduce the speed of the wave from those equations?
