Solution: 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. Some characteristic wavelengths for some of the elements are
Ag 328.1 nm Fe 372.0 nm
Au 267.6 nm K 404.7 nm
Ba 455.4 nm Mg 285.2 nm
Ca 422.7 nm Na 589.6 nm
Cu 324.8 nm Ni 341.5 nm
Which element emits photons of lowest energy?
