Alpha Particle Wave

APPH12-EVKJSE

An alpha particle commonly has a speed of 15,000 km/s.

What is a reasonable value for the de Broglie wavelength of an alpha particle when considered as a matter wave?

A

$\lambda =2.65\times { 10 }^{ -14 }\text{ m}$

B

$\lambda =6.65\times { 10 }^{ -15 }\text{ m}$

C

$\lambda =4.15\times { 10 }^{ -4 }\text{ m}$

D

$\lambda =6.65\times { 10 }^{ -12 }\text{ m}$
