Answer :
Answer:
The transition 6→2, corresponds to the color violet.
The transition 5→2, corresponds to the color blue.
The transition 4→2, corresponds to the color aqua or greenish-blue.
The transition 3→2, corresponds to the color red.
Explanation:
The Balmer series is the second spectral series in the emission spectrum of the hydrogen atom. This series includes the transition from an outer orbit having principal quantum number, n ≥ 3 to orbit having n = 2.
As energy (E) is inversely proportional to wavelength (λ) by the equation, E=hc/λ. So, high energy transition has lower wavelength and low energy transition has higher wavelength.
In the Balmer series:
The transition 6→2 is a high energy transition, so it corresponds to lower wavelength 410.17 and thus the color violet.
The transition 5→2, corresponds to wavelength 434.05 and thus the color blue.
The transition 4→2, corresponds to wavelength 486.14 and thus the color aqua or greenish-blue.
The transition 3→2 is a low energy transition, so it corresponds to higher wavelength 656.45 and thus the color red.
