    I believe your laser has an infrared filter.

    Who is the Best Living Physicist?

    Is the essence of Beauty rational? no, should it then be cast into the ''absurd and utterly idiotic''? Your wording suggests you are trying to be inflammatory and frankly I think that is closed minded. so as to not let this thread but sucked into yet another theological debate, I attach a...

    Who is the Best Living Physicist?

    I couldn't have said it better myself! I happen to like some of Dyson's views, like Anthropogenic global warming hasn't been proven beyond a doubt, but a bit of game theory would spur me to agree that it's a good idea to curb our emissions, just in case, and even if we're wrong at least then...

    Atmospheric Opacity and laser Attenuation query

    May I ask if you have experience with optics in a professional standing? I do not mind if the answer cannot be guessed, I am not afraid of deductive reasoning via mathematics. I do not agree with you in regard to your belief that the ambient atmosphere has unsuitably high scattering...

    So will the detector show greater Intensity from the red laser or Green?

    Atmospheric Opacity and laser Attenuation query

    Well that helps me understand the graph a bit more but in my thought experiment both the light source and measuring are done at sea level.

    Atmospheric Opacity and laser Attenuation query

    I would appreciate assistance with a thought experiment I've been having trouble with. What I asked myself was, If I had two Lasers of equal Intensity/power, say 200 milliwatts, one appearing green and the other red, with wavelenghts of say 555 nanometres and the other 660 nm, which laser...

    How do photons behave when entering a prism?

    Your Punctuation isn't the greatest, but then again, we've all had bad days. As I'm not a great teacher I will save myself the embarrassment of trying to answer your question, but since I had a question similar to yours sometime ago, I kept this page link that helped me understand Dispersion...
