Q. Photon and electron are given same energy $(10^{-20} J)$. Wavelength associated with photon and electron are $\lambda_p$ and $\lambda_e$, the correct statement will be
AIIMS
AIIMS 2012
A
$\lambda_p > \lambda_e$
B
$\lambda_p < \lambda_e$
C
$\lambda_p = \lambda_e$
D
$\frac {\lambda_e} { \lambda_p} = c$
Solution:
Wavelength of photon will be greater than that of electron because mass of photon is less than that of electron
$\Rightarrow \lambda _ p > \lambda_e$
