For the formula λ = h/p (de Broglie), dimensional consistency:
A[h] = ML²T⁻¹, [p] = MLT⁻¹, [h/p] = L = wavelength ✓
BInconsistent
CCannot verify
DRandom
Answer & Solution
Correct answer: A. [h] = ML²T⁻¹, [p] = MLT⁻¹, [h/p] = L = wavelength ✓
[h] = ML²T⁻¹. [p] = MLT⁻¹. [h/p] = ML²T⁻¹ / MLT⁻¹ = L. ✓ Wavelength is L. Consistent.
