It was not electron volt...Q was potential difference is measured in

There was no Q of Compton shift

Dont remember exact Q of heat transfer...but i think it was collision of particles...and it is conduction

and wave nature of electrons/particles was explained by debroglie first in 1924 then experimented by davisson germer in 1927...so it was debroglie...even he got nobel prize for it in 1929...
Questions were ...
electron volt is a unit of ....which is electric force/energy
other one was wave nature of energy was given by ....de broglie gave theory related electrons and plancks regarding light/photon
