Question
A proton of mass '${m_P}$' has same energy as that of a photon of wavelength '$\lambda $'. If the proton is moving at non-relativistic speed, then ratio of its de Broglie wavelength to the wavelength of photon is.
Select the correct option:
A
$\frac{1}{{\rm{c}}}\sqrt {\frac{{\rm{E}}}{{{{\rm{m}}_{\rm{p}}}}}} $
B
$\frac{1}{{\rm{c}}}\sqrt {\frac{{2{\rm{E}}}}{{{{\rm{m}}_{\rm{p}}}}}} $
C
$\frac{1}{{\rm{c}}}\sqrt {\frac{{\rm{E}}}{{2\;{{\rm{m}}_{\rm{p}}}}}} $
D
$\frac{1}{{2{\rm{c}}}}\sqrt {\frac{{\rm{E}}}{{{{\rm{m}}_{\rm{p}}}}}} $
