Its well known that an accelerated charge emits electromagnetic radiation. Then why the orbiting electrons in atom merge in nucleus after some time.

Welcome to PF.GAGAN SHARMA said:Its well known that an accelerated charge emits electromagnetic radiation. Then why the orbiting electrons in atom (do not) merge in nucleus after some time.
Panofsky and Phillips "Classical Electricity and Magnetism" First edition, page 301 eqn(19-19) shows that a uniformly accelerating charge radiates. It is proportional to (dv/dt)2.Andrew Mason said:It may be that your premise is incorrect. Whether a uniformly accelerated charge emits radiation is still a matter of debate.

Well, a charge that accelerates uniformly due to its interaction with an electro-magnetic field will radiate. But is that caused by the interactions of the charge with the field or is it caused by the acceleration?Bob S said:Panofsky and Phillips "Classical Electricity and Magnetism" First edition, page 301 eqn(19-19) shows that a uniformly accelerating charge radiates.

Accelerated charges emit electromagnetic radiation because of the changes in their electric and magnetic fields. When a charge is accelerated, its electric field changes, creating a ripple effect in the surrounding space, which produces a magnetic field. This change in the fields results in the emission of electromagnetic radiation.
The emission of electromagnetic radiation occurs in accelerated charges through a process known as synchrotron radiation. This is when the accelerated charge moves in a curved path, causing its electric and magnetic fields to oscillate, resulting in the emission of electromagnetic radiation.
The amount of electromagnetic radiation emitted by an accelerated charge depends on factors such as the charge's acceleration, the strength of its electric and magnetic fields, and the frequency of the emitted radiation. The higher the acceleration and stronger the fields, the more electromagnetic radiation is emitted.
The emission of electromagnetic radiation is directly related to the speed of the accelerated charge. As the charge's speed increases, its acceleration also increases, resulting in stronger and more frequent changes in the electric and magnetic fields, leading to a higher frequency and intensity of emitted electromagnetic radiation.
Yes, the emission of electromagnetic radiation from an accelerated charge can be controlled by adjusting the charge's acceleration and the strength of its electric and magnetic fields. This is useful in many applications, such as in particle accelerators, where the emission of electromagnetic radiation needs to be precisely controlled for scientific experiments.
