Does infra-red light take more or less enery to produce than ultra-violet light?

And, is the scale of energy requirement on a linear scale, or logarythmic scale?

And, is there a shift in energy requirement between ultra-ultra-violet and ultra-infra-red (far end of the spectrum), or is it (the energy requirement) on the same linear or logarythmic scale?

Per photon the UV has more energy. The blue lasers need a bandgap energy larger than the red ones.

The energy = frequency * h

frequence * wavelength =c or freq. = c/wavelength

h = Plank's constant

Linear relation between energy and frequency

Inverse Linear between eneryg and wavelength
Reply:I would think infra-red takes much less energy than ultra-violet since it is very long wavelength, thus very low frequency (remember, frequency is the inverse of wavelengh). On the other hand, ultra-violet light is very short wavelengh (very high frequency), so I think this requires much more energy. I'm not sure about the linear vs. logarithmic part.
