For the following wavelength determine if the atmospheric emissivity(thus absorptivity) is closer to 0 or closer to 1
Wavelength= 3 micrometers
Please explain I'm not given anything else so I am not sure how to do it. I'm only given the wavelength

I'm not sure how to answer. how do I figure out the
wavelength? or the speed of the wave? can someone please help me
answer these 3 questions? I would appreciate it.
5. For the waves pictured below (physics.stackexchange.com); a. Determine the wavelength. b. If 637 waves pass a point every 241.0 seconds, determine the period and the frequency of the wave. c. What is the speed of the wave?

I think I need to use beer's law. Abs=ebc; e=Abs/bc.
b is 1.66 cm. I think c is .400 M NiSO4, but I'm not sure. I
also think Abs is 0.758 given the graph. (If wavelength is 380 nm,
then it should be between 0.598 and 0.798, right?) My answer is
1.14 L/mol*cm, but not sure if I am...

Give an example of a function f(x, y) that is defined on R2 and has only hyperbolas as its level sets. At the moment I have x2 - y2 = k (where k is a constant) as my answer. But I'm not sure if that is correct. It seems to work except when k = 0, which I'll have only two lines (y = x and y = -x) so I'm not too sure what should I do with it....

Hello Could I please have some guidance on the following question. If an astable waveform (rectangular wave) has a mark/space ratio of 0.33, what would be the Duty Cycle for the same waveform expressed in %? So this is what I know Duty Cycle (DC) = TH / T x 100 Period (T) = TH + TL Mark/Space (MS) = TH / TL So I have managed to get this far with substitution DC = TH/ (TH + TH/ MS)...
