Question 1 of 5

A proton, a neutron, an electron and an \alpha-particle have same energy. If \lambda_{\mathrm{p}}, \lambda_{\mathrm{n}}, \lambda_{\mathrm{e}} and \lambda_{\alpha} are the de Broglie’s wavelengths of proton, neutron, electron and \alpha particle respectively, then choose the correct relation from the following :

A

\lambda_{\mathrm{e}}<\lambda_{\mathrm{p}}=\lambda_{\mathrm{n}}>\lambda_{\alpha}

B

\lambda_{\mathrm{e}}=\lambda_{\mathrm{p}}=\lambda_{\mathrm{n}}=\lambda_{\alpha}

C

\lambda_{\mathrm{p}}=\lambda_{\mathrm{n}}>\lambda_{\mathrm{e}}>\lambda_{\alpha}

D

\lambda_{\alpha}<\lambda_{\mathrm{n}}<\lambda_{\mathrm{p}}<\lambda_{\mathrm{e}}
