Question

What should be the order of arrangement of de-Broglie wavelength of electron ( $\lambda_{\mathrm{e}}$ ), an $\alpha$-particle ( $\lambda_\alpha$ ) and proton ( $\lambda_{\mathrm{p}}$ ) given that all have the same kinetic energy?

Select the correct option:

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

$\lambda_e<\lambda_p<\lambda_\alpha$

$\lambda_e>\lambda_p>\lambda_\alpha$

$\lambda_e=\lambda_p>\lambda_\alpha$
