Is SIMPLE HARMONIC MOTION related to frequency in a radio wave?

I don't really know EXACTLY what you are asking, but I'm going to take a jump here and assume you don't quite know exactly what "frequency" is(correct me if I'm wrong).

Frequency is merely a way to describe something cyclical. For instance, the Si unit for frequency is Hertz, which is one cycle per second. You can use it to describe many things, from cyclical motion, vibration, the wavelength of a sine wave(radio wave) etc.

Harmonic motion usually comes about as a side effect of an underdamped mass/spring/damper(MBK) system. You can use this example to approximate MANY different types of mechanical systems, since everything has a mass and spring constant, and some amount of damping will exist in all physical systems.

So when this underdamped system is oscillating in some manner, there are residual vibrations on the harmonics of the driving frequency. These are simply multiples of the driving frequency(i.e. at 100Hz driving freq., there will be harmonics at 200Hz etc.).

This happens in a variety of systems that aren't mechanical as well, like electrical circuits and sound waves.

Sorry, kept getting a 404 error, but it was actually posting.

Since SHM can be represented by trig, then I guess we could say that SHM is related to frequency measurements.

An electron undergoing simple harmonic motion will radiate a pure sine EM waveform. So the answer to your question is yes.

Anything moving in circular motion can be seen as simple harmonic motion.
