CUET and UG exam CUET UG 2025 Mock Test Series Physics Dual Nature: Photon and Matter Waves The Photoelectric Effect
An electron and an alpha particle are accelerated by the same potential difference. Let λe and λα denote the de Broglie wavelengths of the electron and the alpha particle, respectively, then:
1
λe > λα
2
λe = 4λα
3
λe = λα
4
λe < λα
