Relativity of locality

[questionposter]

So light's frequency is relative, so does that mean light is both most likely to exist in a certain area and also NOT likely to exist in the same area? How can the physical space light occupies be relative? Because to one thing light can be a gamma ray and to another thing it can be a radio wave, but those two wavelengths have different localization patterns. So just because I measure something, it automatically determines the physical space that it exists in for my point of view?

The length you would measure in two frames is not the same.
