how do powerful lasers clean rust etc if lasers are just a form of light?
In: 4
What humans refer to as light is a subatomic particle called a photon.
Lasers are a beam of focused photons.
If you shine that laser onto an object the photons are hitting that object and transferring energy to it mostly in the form of heat.
When enough energy is transferred from the photons to the material in question it will begin to burn ablate or melt depending on the substance in question.
