Which element emits photons of highest energy

Reference no: EM131028501

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:

Ag	328.1nm	Fe	372.0nm
Au	267.6nm	K	404.7nm
Ba	455.4nm	Mg	285.2nm
Ca	422.7nm	Na	589.6nm
Cu	324.8nm	Ni	341.5nm

(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 . 6.59 X 1014 s-1 Which of these elements is probably in the sample?
