?Certain elements emit light of a specific wavelength when they are burned
Chapter 6, Problem 6.83(choose chapter or problem)
Certain elements emit light of a specific wavelength when they are burned. Historically, chemists used such emission wavelengths to determine whether specific elements were present in a sample. Characteristic wavelengths for some of the elements are given in the following table:
(a) Determine which elements emit radiation in the visible part of the spectrum.
(b) Which element emits photons of highest energy? Of lowest energy?
(c) When burned, a sample of an unknown substance is found to emit light of frequency 9.23 1014 s-1. Which of these elements is probably in the sample?
