Question #fc63c
1 Answer
Explanation:
The idea here is that when an electron makes a transition from an energy level to another, the difference in energy between the two levels will be equal to the energy of the photon emitted or absorbed by the electron.
In your case, the two electrons emit photons when making the transitions, so right from the start, you can say that energy level
Now, the energies of the photons emitted during the transitions are directly proportional to the frequencies of the photons, which, in turn, are inversely proportional to their wavelengths.
Now, you know by looking at the visible portion of the EM spectrum that you have
#"B " -> " C" : " "color(blue)("blue light") implies {(ul("high frequency")), ("short wavelength") :} => ul("higher energy photon")#
#"B " -> " A": " "color(red)("red light") implies {(ul("low frequency")), ("long wavelength") :} implies ul("lower energy photon")#
For electron
Consequently, you can say that the difference in energy between energy level
You can thus say that for electron
#"B " stackrel(color(white)(aaaaaaaaaaacolor(blue)("higher energy photon")aaaaaaaaaaaaaa))(color(blue)(->)) " C" #
For electron
#"B " stackrel(color(white)(aaacolor(red)("lower energy photon")aaaaaa))(color(red)(->)) " A"#
