Answer: Certain elements emit light of a specific
Chapter , Problem 83AE(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
\(9.23 X 10^{14} s^{-1}\). Which of these elements is probably in the sample?

ANSWER:
Step 1 of 4
(a)
Visible light waves are the only electromagnetic waves we can see. We can see these waves as the colours of the rainbow.
Visible light emits radiation of wavelengths, in range of
