Plot the following spectroscopic data using MS Excel with each plot on separate Excel work sheet. (a) Plot the chart from 200-850 nm. See Figure 1-4 and note the major charting guidelines (b) Plot the chart from 200-500 nm. (c) Plot the chart from 500-850 nm. (d) What is the value of max. Wavelength (2, nm) Absorbance 0.03 0.09 0.10 Ba Ca Cu Fe K 200 250 300 Mg Na Ni 350 400 450 500 550 600 650 700 750 800 850 Certain elements emit light of a specific wavelength when they are burned, characteristic wavelengths for some of the elements are given in the following table. Element Light of specific wavelength (2, nm) Energy Ag Au 328.1 267.6 0.22 0.15 0.10 0.11 0.15 0.17 0.23 455.4 422.7 324.8 0.57 0.88 372.0 404.7 285.2 589.6 341.5 0.64 0.31 (a) Use Plank's equation to find the energy of each wavelength (b) Which element emits photons of highest energy? (c) Which elements emit radiation in visible region of the electromagnetic radiation? Hints: 1. Plank's equation: E he 2 2.
