Question 164: Atoms & Nuclei

Question

A nucleus of mass $M$ at rest splits into two parts having masses $\frac{M^{\prime}}{3}$ and ${{2M'} \over 3}(M' < M)$. The ratio of de Broglie wavelength of two parts will be :

Accepted Answer

Linear momentum is conserved
so, ${p_{M'/3}} = {p_{2M'/3}}$
so, ${{{\lambda _{M'/3}}} \over {{\lambda _{2M'/3}}}} = {1 \over 1}$
