CUET and UG exam CUET UG 2025 Mock Test Series Physics Dual Nature: Photon and Matter Waves The Hydrogen Atom
Energy levels A, B, C of a certain atom correspond to increasing value of energy Eᴀ < Eʙ < Eᴄ. If λ₁, λ₂, λ₃ are the wavelengths of radiation corresponding to the transitions C → B, B → A and C → A respectively, then:
1
λ₃ = λ₁ + λ₂
2
λ₁ = λ₂ = λ₃
3
λ₃² = λ₁² + λ₂²
4
\(\lambda_3 = \frac{\lambda_1 \lambda_2}{\lambda_1 + \lambda_2}\)
