Are wavelengths well defined or vague?

    As in, for example, boundaries between UV and visible, UV-A and UV-B, blue and purple, gamma rays and x-rays. Or are they ill-defined and subject to the Sorites Paradox?

    Also, does anyone know if there is a highest level of energy a gamma ray can have?

    Thanks!

    There are some bands with very widely-accepted boundaries, but, for the most part, the boundaries are vague. There is no limit to gamma ray energy.

    Okay. Which are the widely accepted boundaries? And what's the highest energy gamma ray ever detected? (I would suspect that it came from some quasar)... Though since all energy sources are emitted from a blackbody spectrum, there would be comparatively few photons of such wavelengths
