The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Claim**: The statement claims that "The dual nature of electron was given by Sommerfeld." 2. **Evaluate the Claim**: To determine if the statement is true or false, we need to recall who actually proposed the dual nature of the electron. 3. **Correct Attribution**: The dual nature of the electron, which refers to the concept that electrons exhibit both particle-like and wave-like properties, was proposed by Louis de Broglie, not Sommerfeld. 4. **Mathematical Expression**: De Broglie introduced a mathematical expression to describe the wavelength (λ) of a particle, which is given by the formula: \[ \lambda = \frac{h}{p} \] where: - \( \lambda \) = wavelength - \( h \) = Planck's constant - \( p \) = momentum of the particle 5. **Momentum Relation**: Momentum (p) can also be expressed in terms of mass (m) and velocity (v): \[ p = mv \] Therefore, we can rewrite the wavelength formula as: \[ \lambda = \frac{h}{mv} \] 6. **Conclusion**: Since the original statement attributed the dual nature of the electron to Sommerfeld, and it is actually attributed to de Broglie, the statement is false. 7. **Final Statement**: The correct attribution is that "The dual nature of the electron was proposed by Louis de Broglie." ---
