Electron de Broglie Wavelength

APPH12-YQE$R3

An electron is accelerated by a potential difference, reaching a speed of $6.0\times { 10 }^{ 6 }\text{ m/s}$.

What is a wavelength of a matter wave which is consistent with this information?

A

$\lambda =8.24\times { 1 }0^{ 9 }\text{ m}$

B

$\lambda =7.56\times { 10 }^{ 8 }\text{ m}$

C

$\lambda =6.89\times { 10 }^{ -22 }\text{ m}$

D

$\lambda =1.2\times { 10 }^{ -10 }\text{ m}$
