MCQ
Photon and electron are given same energy $(\left.10^{-20} \mathrm{~J}\right).$ Wavelength associated with photon and electron are $\lambda_{\text {ph }}$ and $\lambda_{\mathrm{el}}$ then correct statement will be
  • $\lambda_{\mathrm{ph}}>\lambda_{\mathrm{el}}$
  • B
    $\lambda_{\text {ph }}<\lambda_{\text {el }}$
  • C
    $\lambda_{\mathrm{ph}}=\lambda_{\mathrm{el}}$
  • D
    $\frac{\lambda_{\mathrm{ph}}}{\lambda_{\mathrm{el}}}=\mathrm{C}$

Answer

Correct option: A.
$\lambda_{\mathrm{ph}}>\lambda_{\mathrm{el}}$
$\lambda_{\mathrm{ph}}>\lambda_{\mathrm{el}}$
