What would the properties of an infinitely long wavelength of light be? And what about a wavelength of light that is infinitely short? What would that look like?

edit: light as in electromagnetic waves, not visible light. Sorry if it was not very clear

    The idea that a very small wavelength would cause a black hole doesn’t really make sense to me since I thought a black hole requires mass. I’m no physicist, so I don’t really know.

    However, a search about light with a Planck wavelength came up with this result which seems to claim that eventually the wavelength would become so small as to no longer be capable of holding information and would essentially do nothing.

      It’s mass OR energy.

      Light, even though massless will still bend (and be affected by distorted) spacetime because it has energy in form of momentum. (See: gravitational lensing).

        It is affected by gravity. But does it have gravitational pull? The thing about black holes is that they have a lot gravitational pull.

        I’m asking because I honestly don’t know.

          They do indeed. It’s totally minuscule of course.

          Everything that has energy deforms spacetime and spacetime affects how anything with energy moves.
