Why Accelerated Charge Radiates Energy?

Remember, acceleration means its velocity needs to change, which can be achieved either by changing the electron's speed or its direction. Both types of change will produce an acceleration, and hence produce EM radiation

EM radiation
Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 gigahertz (GHz) to as low as 30 hertz (Hz). ... Radio waves are generated artificially by transmitters and received by radio receivers, using antennas.

How do accelerated charges radiate energy?

It is well known that accelerated charges emit electromagnetic radiation. ... Joseph Larmor published the first analysis, in 1895, conerning radiation by an accelerated charge based upon the derivation by Hendrik Lorentz of the force experienced by a particle due its charge field being dragged through the ether.

Does a uniformly accelerating charge radiates?

Since such radiation is not observed, a uniformly accelerated charge can not radiate.
