I agree with I also think it's D) 940 nm because it is beyond the visible spectrum.

I think the answer is D) 940 nm because higher wavelengths are usually invisible.

Haha, I bet the exam writers are hoping we'll all get tripped up on this one. They love to throw in those little twists and turns, don't they?

Hmm, I'm leaning towards 940 nm as the answer. That's pretty deep in the infrared range, so I don't think it would produce any visible glow.

I believe only wavelengths beyond 940 nm would not produce any visible glow.

But what about 850 nm? Could that also not produce any visible glow?

Agreed. The shorter wavelengths, like 650 nm and 750 nm, are probably going to be in the visible spectrum and produce a glow.

Okay, let's think this through. I'm guessing the longer wavelengths, like 850 nm and 940 nm, are more likely to be invisible to the human eye.

Yeah, I was thinking the same thing. It's not just about the wavelength, but whether it produces a visible glow or not.

Hmm, this question seems to be testing our knowledge of infrared (IR) illuminators. I wonder if they're trying to catch us out with the visible glow aspect.
