उत्तर
Specify the transition of an electron in the wavelength of the line in the Bohr model of the hydrogen atom which gives rise to the spectral line of the highest wavelength n = 3 to n = 2.
Explanation:
The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency result in lower energy. The energy equation is E = hv.
The amount of energy is directly proportional to `[1/n_1^2 - 1/n_2^2]`.
When the energy difference is low the wavelength will be highest, which is in n = 3 to n = 2.
