Want this question answered?
The electric and the magnetic field components.
An Electromagnetic Wave
Amplitude times frequency.
spectrum of sinewave contains how many components The spectrum of a pure sine wave by definition has only one component. Any other periodic wave will additional components at multiples of the fundemental frequency. The spectrum may or may not extend to infinity. A square wave for example has infinite harmonics, the harmonics of a 'modified sine wave' inverter has lower harmonics than a square wave but still has infinite harmonics. As you get closer to a pure sinusiod the energy content of the higher harmonics will be essentially non existent. It all depends how close the wave approximates a pure sinusoid.
I use the "Wave Builder- Wave Tex" texturizer kit. it has 5 different components, clear instructions, and works well. (note: make sure to follow the instructions very carefully!)
The electric and the magnetic field components.
The energy travels parallel to the direction of the wave
An Electromagnetic Wave
Speed, wavelength and frequency.

The EKG or ECG components are the P wave (contraction of the atria), the QRS complex (the contraction of the ventricles) and the T wave (repolarization of the ventricles).
the components of the earth are actually the pacific ocean atlatic ocean and others. the components are describe by they are like a wave.
Electromagnetic waves do not require a medium to travel (light, radio).

The source is the RF current in the transmitting antenna.
