Question

In 2-3 sentences, explain an example in which electromagnetic radiation other than visible light can be used to show us more about an object than visible light alone.

Answer 1

Infrared radiation can be used to reveal thermal properties of objects that are not detectable by visible light, such as identifying heat loss in buildings or locating hidden moisture leaks. For instance, thermal imaging cameras capture infrared radiation emitted by objects, allowing us to visualize temperature differences and detect issues like insulation failures or electrical overheating, which would be invisible to the naked eye.
