Explain why the classical theory of light as an electromagneticwave (or of electrons as particles) is unable to explain thefollowing phenomena whereas quantum mechanics is successful.
(1) The turn-on voltage of differently colored LEDs
(2) The existence of transparent conductors
(3) The decrease in frequency of photons scattered off ofatoms
(4) The spectrum of blackbody emission
For each, use 2-3 sentences, 1-2 equations, and a diagram toprovide an explanation that is concise yet precise.
