Radiasi elektromagnetik mana yang digunakan untuk peralatan pemanas dan penglihatan malam
Infrared
Infrared: Night vision goggles pick up the infrared light emitted
by our skin and objects with heat.
In space, infrared light helps us map the dust between stars.
Visible: Our eyes detect visible light.
Fireflies, light bulbs, and stars all emit visible light.
