Question 210: 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, $${{{\lambda _{M'/3}}} \over {{\lambda _{2M'/3}}}} = {1 \over 1}$$
