In the graph below the excitation (dashed line) and emission (solid line) spectra of a certain fluorescent dye is shown. To the nearest 5 nm, what is the peak emission wavelength of this dye? 3.80 430 480 530 wavelength (nm) Type your answer... 580 <--Excitation Emission 630

3. What are K,L and M lines you discovered in the Moseley's law experi- ment ? 4. What is the Duane Hunt maximum x-ray frequency of a excitation voltage V = 6kV ? 5. Draw a basic shape of the x-ray absorption spectrum of a generic element, denote the Band a lines along with Duane-Hunt cutoff

Use the worked example above to help you solve this problem. A sodium surface is illuminated with light of wavelength 0.329 µm. The work function for sodium is 2.46 eV.

how would you answer this? The maximum kinetic energy of photoelectrons is plotted as a function of the frequency of incident light. The slope of this graph is.. would appreciate work shown for this question, thanks   a Planck’s constant. b Rydberg’s constant. c Coulomb’s constant. d Newton’s gravitational constant.
