Basically light wavelengths have different “distance”/frequency, which we observe as different colours (measured in nm), UV IR etc are not detectable by eye. The wavelengths (“distance”) needs to be identical distance in bonds between atoms or electrons to interact and pass energy (which is why light can heat up materials), if distance is not perfect it just passed through like in case of visible light and glass. Some one check I’m pretty sure it’s correct
