Question 142: Dual Nature of Matter and Radiation

Question

An electron of mass m
e
and a proton of mass m
p
are accelerated through the same potential difference. The ratio of the de-Broglie wavelength associated with the electron to that with the proton is

Accepted Answer

$$\lambda  = {h \over p} = {h \over {\sqrt {2km} }}$$
$${{{\lambda _e}} \over {{\lambda _p}}} = \sqrt {{{{k_p}{m_p}} \over {{k_e}{m_e}}}}  = \sqrt {{{{m_p}} \over {{m_e}}}} $$

Answer

$${{{m_e}} \over {{m_p}}}$$

Answer

1

Answer

$${{{m_p}} \over {{m_e}}}$$

Answer

$$\sqrt {{{{m_p}} \over {{m_e}}}} $$
