Compton Effect conceptual problem

[kraphysics]

Explain why the Compton effect provides critical evidence for the particle model of light.

I know the Compton effect proved that light has momentum but not sure how that is evidence for particle model of light. Can someone help?

only particle can change state of another particle in an inertial frame... you can really move your radio with radio waves ,, can you?

But it doesn't change the state. I am confused. What do you mean?

It DO change the state ...
if it doesn't then ehy do you think NASA is planning to send satellites that will use photons to travel?
