Ambiguos

Infrared radiation is invisible because its wavelength— 0.1 millimeters—is too long for the eye to register it.

ETS : IT (bolded above) is ambiguous...

Can someone help me understand why IT cannot refer to Infrared radiation?

'It' is actually redundant and would be better omitted. By common sense we recognize that 'it' is the nearer of the nouns; the wavelength is 'it', since an actual measurement ('too long to register') is given in the sentence.
