what is the wavelength (in nm) of the green laser?

I'm not certain of the exact wavelength, but it is a bright green beam, so it falls somewhere between 495 nm and 570 nm. There is nothing on the presenter itself or in the packaging that states a definite wavelength.

Does this work with adoble acrobat reader? i want to be able to click to the next page in a pdf from afar. thank you!

Full disclosure: I have a 2018 MacBook Pro, so I have not attempted the same thing on a PC. Using Adobe Reader, I was able to scroll up and down a single page with the Knorvay presentation remote in the regular viewing screen. When in Full-Screen mode, it was able to advance to the next page or reverse to the prior page, if needed. I hope you find this helpful.
