Question

An electron and a proton are moving with the same velocity. Find the ratios of de-broglie wavelength

Answer 1

Answer:

$\frac{1}{1840}$

Explanation:

De Broglie wavelength is given by:

λ= $\frac{h}{p}$

If two bodies (electron and proton) have the same De Broglie wavelength, they have the same momentum.

i.e.

p₁ = p₂

$m_{e}$$v_{e}$ = $m_{p} v_{p}$

i.e.

$\frac{m_{e} }{m_{p} }$ = $\frac{v_{p} }{v_{e} }$

= $\frac{1}{1840}$
