Question

How do we feel the energy of infrared waves?

Answer 1

we feel infrared waves from the heat that they produce

Answer 2

When an object is not quite hot enough to radiate visible light, it will emit most of its energy in the infrared. For example, hot charcoal may not give off light but it does emit infrared radiation which we feel as heat. The warmer the object, the more infrared radiation it emits.

hope this helped :)
