Assertion According to de Broglie, the wavelengths associtated with electrons and other subatomic particles can be detected experimentally. Reason The wavelength associated with any material particle is directly proportional to its mass.
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- C. Assertion is correct but Reason is incorrect
- D. Both Assertion and Reason are incorrect
Step-by-step solution
The assertion is correct because de Broglie's hypothesis of wave-particle duality for matter has been experimentally verified, e.g., by electron diffraction. The reason is incorrect because de Broglie's relation λ = h/p shows wavelength is inversely proportional to momentum (mass × velocity), not directly proportional to mass.
