In general the energy conveyed by an electromagnetic wave, like a radiowave, in a second (the power P) can be evaluated by the modulus of the Poynting vector S of the wave, that is given by the vector product of the electrical and the magnetic fields vectors E and H respectively (bold letters indicates vectors)
Thus
P=| S |=| E X H |
If no charges are present there is a precise relation between the vectors E and H and the power can be evaluated also starting only from the electrical field E as
P=(eps/mu) | E |2
where eps is the dielectric constant of the medium and mu its magnetic permittivity.
radiowave+fier
Both. A radio wave is an electromagnetic wave; therefore it is a transverse wave.
Radio waves as low as 10kHz frequencies are used, and the radiowave spectrum gradually passes through the millimeter waves into the Infra Red, then the Visible and Ultra Violet regions, up into the X-ray and then the gamma ray regions, by which time, the wavelength is so short, that one may consider them as particles.

radiowave+radiowave
Very low energy light. Wavelengths usually longer than 1 meter.
radiowave+radiowave= radiation
void and electricity make radiowave
Void (acquired after inventing 100elements) + Electricity (Energy + Metal) = Radio Wave
To make the cellphone you need to put radiowave and computer together (radiowave and computer)
radiowave+fier
Void + electricity
lightbulb+radiowave :D
Radiowave + lightbulb = tv
Void + electricity = Radio Wave
