If energy increases with decreasing wavelength, then...

[Sam_A]

..then a wavelength of zero nanometers has infinite energy?

 

[mfb]

There is no "wavelength of zero nanometers".

 

[Sam_A]

There is no "wavelength of zero nanometers".

Okay, how about.. as the wavelength approaches zero nanometers, the energy approaches infinity? Is there a limit in this?

The energy per photon, yes.
There is no proper limit.
