Practicing Success
A proton and a triton are accelerated from rest through a potential V. The ratio of their de Broglie wavelength is: |
1 : 1 1 : 2 1 : $\sqrt{2}$ $\sqrt{3}$ : 1 |
$\sqrt{3}$ : 1 |
The correct answer is Option (4) → $\sqrt{3}$ : 1 de-Broglie wavelength of a charge moving in a electric field $\lambda=\frac{h}{\sqrt{2 m q V}}$ Mass of triton = 3 (mass of proton) $\frac{\lambda_1}{\lambda_2}=\sqrt{3}: 1$ |
