JEE Mains · Physics · STD 12 - 11. Dual nature of radiation and matter
A nucleus of mass \(M\) at rest splits into two parts having masses \(\frac{M^{\prime}}{3}\) and \(\frac{2 M^{\prime}}{3}\left(M^{\prime} < M\right)\). The ratio of de Broglie wavelength of two parts will be.
- A \(1:2\)
- B \(2:1\)
- C \(1:1\)
- D \(2:3\)
Answer & Solution
Correct Answer
(C) \(1:1\)
Step-by-step Solution
Detailed explanation
\(\left|\overrightarrow{ P }_{1}\right|=\left|\overrightarrow{ P }_{2}\right|\) Here \(\overrightarrow{ P }\) is momentum So \(\lambda=\frac{ h }{ P }\) Hence both will have same de broglie wavelength.
