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.
You’re telling me only visible light counts as light to lasers?
Yes, light is usually defined as the part of the EM spectrum the (human) eye is capable of perceiving..
