Question

Why did Chadwick thought that the emerging particles on radiations were not photons?

• A. Energy of the emerging particles was very low as compared to photon
• B. Energy of the emerging particles was equal to photon
• C. Energy of the emerging particles was much more than the photons
• D. None of the above

Answer 1

The correct option is C Energy of the emerging particles was much more than the photons

Chadwick carried out the experiments, using many different elements as radiation targets besides paraffin. By comparing the energies of particles ejected from all these various targets, Chadwick was able to prove that the radiation causing the ejected particles was much more energetic than could be accounted for by photons.
