Question

An electron of mass m and a photon have same energy E. The ratio of wavelength of electron to that of photon is : (c being the velocity of light)

Select the correct option:

$\frac{1}{c}\left(\frac{2 m}{E}\right)^{1 / 2}$

$\frac{1}{c}\left(\frac{E}{2 m}\right)^{1 / 2}$

$\left(\frac{E}{2 m}\right)^{1 / 2}$

$c(2 m E)^{1 / 2}$
