sixwheeledbeast has quite some point with his suggestion to use LEDs in the 850nm range. For those you should get specifications and redo the math.
Well OK, but nobody corrected me.
You don't measure frequency in distance and you don't buy IR LED's by frequency.
Yes, you are correct that wavelength and frequency oppose each other in the scale of waves.

Also if possible try even lower wavelength like 740nm, they will be even more visible but you will get better images and spread of light at close range.
Also different LED cases make a difference as to how even the light is spread, they can be bought in a variety of "spread" angles
