X-rays from copper ( Kalpha1.54 A, Kbeta 1.39 A, Kabs 1.38A) are passed through a sheet of nickel (Kalpha 1.66A, Kbeta 1.50 A, Kabs 1.49A) what intense wavelengths emerge?the answer is 1.54 Ahow? I have no idea where to even start on this problem. Can someone please set up and explain this problem to me?
theres a yellow tee-handle thats marked transmission fluid pull out that dip stick and put the fliud in there
Life is very tough at times. you should find a way to relax. I recommend not doing your homework and being lazy. If you can keep that up, you'd be well on your way to a happier lifestyle.
I think what you are looking for is the absorption edge for nickel. I used to work with x-rays in powder diffractometry and this sort of work requires a monochromatic source of x ray radiation. The kalpha line was the one that was kept (being the most intense) while the k beta line was the one attenuated (but, not to zero) using a nickel filter working with a copper x-ray tube. What emerged out the other side of the filter was essentially only the kalpha part. However, even the kalpha is not one peak, but two;however, these peaks are so close together that what emerging was essentially considered as monochromatic. (side note: You can only split or detect these two peaks using wavelength dispersive analysis). Different target sources will require different filters. For example, a x-ray tube with a copper target required a nickel filter; while a Cobalt target required a Fe filter.
