    Would the night sky appear dark if our eyes were sensitive to electromagnetic radiation with wavelength around 2 mm? Why or why not?

    Thats the peak of the microwave background - so where ever you looked you would be seeing uwave background. Depends how sensitive your uwave eyes are!
    Incidently the sky is fairly transparent at 2mm.
