Teaching NVS PGT 2024 Test Series Physics Dual Nature: Photon and Matter Waves The Photon, the Quantum of Light
A nucleus A, with a finite de-Broglie wavelength λA, undergoes spontaneous fission into two nuclei B and C of equal mass. B flies in the same direction as that of A, while C files in the opposite direction with a velocity equal to half of that of B. The de-Broglie wavelengths λB and λC of B and C are respectively:
1
λA, 2λA
2
2λA, λA
3
\({{\rm{\lambda }}_{{\rm{A'}}}}\frac{{{{\rm{\lambda }}_{\rm{A}}}}}{2}\)
4
\(\frac{{{{\rm{\lambda }}_{\rm{A}}}}}{2},{{\rm{\lambda }}_{\rm{A}}}\)
