The ratio of the de-Broglie wavelengths for the electron and proton moving with the same velocity is \(\left(m_p\right.\)-mass of proton, \(m_e\)-mass of electron)
- A \(m_p: m_e\)
- B \(m_p^2: m_e^2\)
- C \(m_e: m_p\)
- D \(m_e^2: m_p^2\)
Answer & Solution
Correct Answer
(A) \(m_p: m_e\)
Step-by-step Solution
Detailed explanation
As, we know that de-Broglie wave lengths \(\lambda=\frac{h}{m v} \Rightarrow \lambda \propto \frac{1}{m} \text { So, } \frac{\lambda_e}{\lambda_p}=\frac{m_p}{m_e}\)
