PhysicsEasysingle choice

An $α$ particle and a deuteron are moving with velocities $v$ and $2 v$ respectively. What will be the ratio of their de - Broglie wavelengths?

Options:

Answer:

Solution:

De - Broglie wave length $λ = \frac{h}{P}$

$\frac{λ_{α}}{λ_{D}} = \frac{P_{α}}{P_{D}} = \frac{m_{α} V_{α}}{m_{D} V_{D}}$

$= \frac{4}{2} \times \frac{V}{2 V} = 1$
