"A charge that is accelerated will produce variable electric and magnetic fields. These are electromagnetic waves. If the charge oscillates with a frequency f, then the resulting EM wave will have a frequency f. If the charge ceases to oscillate, then the EM wave is a pulse."
That is what i read but in some cases charges do not oscillate, they just accelerate but yet its said that they produce the electromagnetic waves of some frequency ?
Is the concept of frequency also applied to non oscillating waves ? What would be the cycle of those waves which are just variable but not oscillating ?
