Hello, This is a follow-up question for part b.     For part "b", I supposed that the wavelength of maximum intensity for the following elements is: 1) Sun: 0.500µm 2) Light bulb: 0.966µm  3) Earth: 9.659µm Please note that these measurements are merely hypothetical and are not the actual wavelength radiations.  These are just random numbers.    Can you help me understand the formula for part "c" so that I can implement the answers from part "b" and figure out the temperatures of the sun, light bulb, and the Earth?   Thank you, -Fredrick Beckmann

Explain the process by which an energy dispersive X-ray spectrum (EDX) spectrum is generated and the origins of the La and Ka lines for Fe in the EDX shown in Figure 3 below. Why do the Fe La lines have a lower energy than the Ka lines? By considering the energy of the X-rays measured, discuss whether EDX can be used to measure whether the iron in an iron oxide is in 2+ or 3+ valence state? Which other spectroscopy technique in the transmission electron microscope (TEM) is more appropriate and why? OK 0.01 10.00 kev Figure 3: EDX spectrum of multi-element glass (NIST K309) containing 0, Al, Si, Ca, Ba and Fe.

Write each number in positional numeration. a. The U.S. trade balance in May 2,010 was -$4.23 × 1010. What is -$4.23 × 1010 in positional numeration? $ b. The wavelength of X-rays in inches is 1.2 x 10. What is 1.2 x 10 in positional numeration?

The K series of the discrete spectrum of tungsten contains wavelengths of 0.0185 nm, 0.0209 nm, and 0.0215 nm. The K-shell ionization energy is 69.5 keV. Determine the ionization energies of the L, M, and N shells. Step 1 Characteristic x-rays of the K series are produced when an electron in an upper energy level of a many- electron atom drops down to fill a vacancy in the K (n = 1) shell. Assuming that the given wavelengths are the three longest wavelengths in the K series of tungsten, the transitions that produce them are from the N (n 4) shell to the K shell, from the M (n = 3) shell to the K shell, and from the L (n = 2) shell to the K shell, respectively. These transitions are shown in the energy level diagram, where 1, = 0.0185 nm, = 0.0209 nm, and 13 12 EK = 0.0215 nm. If the ionization energy of the K shell is 69.5 keV, then = -69.5 keV.
