For convenience sake let’s say you have 2 identical lasers, one is blue and one is red. And you shine it on lead (so none of the light leaks through) until the lead doesn’t heat up anymore. Would the temperature change at all between the different color lasers. It doesn’t have to be red or blue, it could be microwave or x ray, just different colors is nessisary.

    Basically, a material can be more or less “translucent” in certain frequencies. I’d like to look lead up for you, but Google isn’t cooperating today. But basically, there are frequencies that lead will be more and less susceptible to.

    For macroscopic objects, there really isn’t a single answer. Something as generic as “a plate of lead(oxide)” can be all over the spectrum depending on texture, exact composition, oxidation levels, etc etc. there’s a reason why lab-grade filters and mirrors cost so much money, it’s hard to get a narrow frequency range.

    It also rapidly changes as the material heats up, melts, breaks down, reacts with the air, etc.
