The electron transition from n=4 to n=2 in a hydrogen atom corresponds to the emission of a photon with a specific wavelength. This wavelength can be calculated using the Rydberg formula:
1/λ = R(1/n2 - 1/n1)
where λ is the wavelength of the emitted photon, R is the Rydberg constant (1.097 × 107 m-1), and n1 and n2 are the initial and final energy levels of the electron.
Substituting n1 = 4 and n2 = 2, we get:
1/λ = R(1/22 - 1/42) = 3R/8
Solving for λ, we get:
λ = 8/3R = 656.3 nm
This wavelength corresponds to the red region of the spectrum, so the correct answer is option (b) Red.
1/λ = R(1/n2 - 1/n1)
