Wave Nature of Electrons
- whatthebleep.com

 

  

D) Matter Waves - ALL moving particles have wave properties.

 

 

 

Louis de Broglie

 

 

λ = h/p = h/mv

 

 

p = momentum of the particle

λ - called DeBroglie Wavelength

h - Planck's constant

 

 

 

The wavelength of ordinary objects are insignificant because their masses are too large.

 


BUT…

 

 Electrons are small enough

to have a significant
wave behavior.

 

 

 

 

1927- Diffraction and interference patterns were observed for electrons.

 

 

A scientist passed electrons through tiny double slits and observed interference patterns

 

Where did they get slits small enough
 and close enough?

 

 

 

 

When you pass a beam of electrons through the slits of a crystal you get an interference pattern

 


 

 

Final Summary

  

IS LIGHT A WAVE OR A PARTICLE?

 

 

 

 

 



Light behaves like a
wave
in interaction
with large objects

and like particle with very small objects
 like electrons
