[dannie]

What quantity measured in the Compton effect experiment shows the wave- particle duality of light?

the momentum shows the wave particle duality of light.
is this true?
The Compton Effect is An increase in wavelength of X-rays or gamma rays that occurs when they are scattered.

 

[Simon Bridge]

You can check - how is momentum delivered in a wave compared with a particle ... compare with how it is delivered in the Compton Effect.
