Photons Wavelength

In summary, there is no limit to how small a change in wavelength can be and it is not quantized. The precision of measuring wavelength depends on the available energy and signal to noise ratio. However, the uncertainty principle states that the energy and therefore the wavelength of a photon cannot be known exactly. This means that while there may be technological limits to measuring wavelength, the ultimate limit is due to the uncertainty principle.

Potentially. There's something called a Planck length that could be the limiting lower size of anything in the Universe. The problem is it's not something we're near being able to test, so it's very hypothetical. You can read more about it and what the consequences of it could be here https://newt.phys.unsw.edu.au/einsteinlight/jw/module6_Planck.htm

It also covers a bit if the other part of your question, but many before me have already addressed that.

Hope that helps

It helped me---I write sci fi and this site -above was excellently explained. Thank you
