Oscillating charge, wave shift

[Hydr0matic]

Consider a charge oscillating along the Y axis. EM waves are emitted around it and hits an observer further down the X axis. The charge then gains speed along the X axis, moving towards the observer. He notes a blueshift in the measured EM wave, ie the Doppler effect.

My question is... Will any movement of the charge along the X axis, no matter how small, shift the wave measured by the observer?

I would say that any movement of the charge, no matter how small, will indeed cause a shift in the measured EM wave by the observer. This is due to the Doppler effect, which occurs when there is relative motion between the source of the wave (the oscillating charge) and the observer.

In this scenario, as the charge gains speed along the X axis and moves towards the observer, the observer will perceive a blueshift in the measured EM wave. This is because the observer is essentially "chasing" the wave, as the charge is moving towards them and causing the wavelength to appear shorter.

Additionally, even if the charge were to have a very small movement along the X axis, it would still cause a slight shift in the measured wave. This is because the Doppler effect is dependent on the relative velocity between the source and the observer, rather than the absolute velocity of the source itself.

In conclusion, any movement of the charge along the X axis, no matter how small, will result in a shift in the measured EM wave by the observer due to the Doppler effect. This is an important concept to consider when studying oscillating charges and their emission of EM waves.
