Infrared energy can be:

Seen with the naked eye
Heard as a low hum
Felt as heat on the skin
Used to improve Wi-Fi signals

The correct answer is: Felt as heat on the skin

Infrared energy is a type of electromagnetic radiation that is not visible to the naked eye. This means that option A, seeing it with the naked eye, is incorrect. Additionally, since it is not a sound wave, it cannot be heard, making option B incorrect as well. Infrared energy is primarily felt as heat on the skin, making option C the correct answer. Option D is incorrect because while infrared can be used to improve Wi-Fi signals, this is not its primary purpose or function.
