An x-ray with a wavelength of 90nm or 2nm? Short reasoning? Im confused?

The X-rays of 2nm will be more energetic. Shorter the wave length, higher the frequency and higher the frequency, higher the energy, which is given by Planck's constant multiplied by frequency.
E = h.nu where E is the energy of the photon, h is the Planck's constant and nu (the greek equivalent of n) is frequency.
Frequency and wavelength are related by c = nu.lambda (where lambda is the wavelength) and c is the velocity of the light / electromagentic radiation which is constant in a given medium.
X- rays and gamma rays are forms of electromagnetic radiation which includes visible light, ultraviolet, infrared, microwave and radiowave regions too.

the formula is
E =hc/wavelength
So ,immediately 90nm is longer than 2nm
The X-ray 2nm has an energy 90/2 =45 this of 90nm

the shorter the wavelength, the higher the energy.
If radio waves (longer wavelength) has higher energy, we all are affected seriously by it already..
