Please Help, Electromagnetic waves and their collision

Hello everyone, My Name is Dwayne McIntosh.

I am not that good at Physics or Mathematics however i do have a problem.

I was brainstorming the other day and i wanted to know, what if one was to use say electromagnetic waves (may be different wavelength,frequency or Photon Energy, but with the same property;passing through solid objects) and make them collide, would the collision produce heat?

I hope this is not a dumb question


If yes, then how do i calculate that heat energy
