Question

Calculate the wavelength of the second line of Lyman series in a spectrum of hydrogen atom. (Take Rydberg constant, R = 1·1 × 10⁷ m⁻¹)

State Bohr's quantization condition for defining stationary orbits.

Use the energy level diagram shown below to obtain the relation between three wavelengths λ₁, λ₂ and λ₃ emitted due to the transition of electron from the energy states C and B.

If the electron in hydrogen atoms is excited to n = 5 state, the number of different frequencies of radiation which may be emitted is:
