Is an electromagnetic wave produced by a charge moving with a constant velocity and accelerated proton emits electromagnetic radiation?
Respected Sir, Rk Naresh
Yes, both scenarios you mentioned involve the emission of electromagnetic radiation, but they occur under different circumstances.
A charge moving at constant velocity also cannot produce electromagnetic waves as the constant motion means that there is no change in the electric and magnetic field of the moving charge. The electromagnetic waves are produced only when an electric charge undergoes acceleration or deceleration. An oscillating or accelerated charge is supposed to be source of an electromagnetic wave. An oscillating charge produces an oscillating electric field in space which further produces an oscillating magnetic field which in turn is a source of electric field. Charged particle is moving with a constant velocity then it equivalent to an electric current which creates the magnetic field and electric field both around it. An accelerated charge, such as an accelerated proton, does emit electromagnetic radiation. This is because acceleration involves a change in velocity over time, leading to changes in the electric and magnetic fields surrounding the charge. Charged particles such as electrons and protons create electromagnetic fields when they move, and these fields transport the type of energy we call electromagnetic radiation, or light. An accelerating charged particle produces an electromagnetic (EM) wave. Electromagnetic waves are electric and magnetic fields traveling through empty space with the speed of light c. A charged particle oscillating about an equilibrium position is an accelerating charged particle. Electromagnetic waves are created by oscillating charges and have the same frequency as the oscillation. Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave.An accelerated point charge emits energy and impulses in the form of radiation. The reason for this attribution is the presence of emitted energy in the form of oscillations of the particle's electromagnetic field in regions relatively far from the particle; these make up the radiation field.
No, a charge moving with a constant velocity does not emit electromagnetic radiation.
Electromagnetic radiation is produced by accelerated charges. This is because acceleration involves a change in velocity over time. When a charged particle accelerates, it creates fluctuations in the electric and magnetic fields surrounding it. These fluctuations propagate outward as electromagnetic waves.
In contrast, a charge moving at a constant velocity has a stable electric field around it. Since the field isn't changing, it doesn't generate any electromagnetic waves.

The electromagnetic waves are produced only when an electric charge undergoes acceleration or deceleration. All of these electromagnetic waves (whether radio, visible or gamma) travel at the same speed. They all travel at the 'speed of light' through a vacuum that is at 3 × 10 8 m s-1. An accelerating charged particle produces an electromagnetic (EM) wave. Electromagnetic waves are electric and magnetic fields traveling through empty space with the speed of light c. A charged particle oscillating about an equilibrium position is an accelerating charged particle.
In addition to all previous answer, Dear Prof. Rk Naresh I advice to read chapter VIII of Vol. 2 "The classical theory of fields" by Profs. L. Landau and E. Lifshitz, i.e., "the field of moving charges".
Best Regards.
maybe one should add that usually charged particles are travelling inside a metallic beampipe and even when they are accelerated (transversely or longitudinal) they would NOT emit EM waves below waveguide cuff.
What will happen in the case of a uniformly moving charge with an accelerated moving observer? Indeed, in relation to it, a uniformly moving charge should be considered as accelerating.
And vice versa, if a proton is accelerated and an observer is accelerated synchronously with it, then in relation to the observer the proton will remain motionless and for such an observer the electric field of the proton will be stationary. Does this mean that for a coherently accelerated observer, the radiation of an accelerated proton will not exist?
And the second question. If we consider two charges moving towards each other, then with constant motion of each of them, the interference pattern of the resulting electric field will change in time. Shouldn't electromagnetic radiation arise if the charges move in an external magnetic field?
I believe that in this context, the answers given above require clarification of the wording
