it is artifical intelligence and 2 more thingks

Explanation:

Answer 2

Electromagnetic waves

Explanation:

• Electromagnetic waves are transverse wave. All objects are continually absorbing and emitting infrared emission, affecting their temperatures.
• Infrared (IR) light is employed by electrical heaters, cookers for cooking food, short-range communications like remote controls, optical fibers, security systems and thermal imaging cameras which detect people within the dark. The heating effect of IR causes burnings in the skin.
• Infrared light has frequencies that have been absorbed by some chemical bonds. the inner energy of the bonds increases once they absorb infrared emission, which causes heating.
• This makes infrared emission useful for electrical heaters and for cooking food. All objects emit actinic ray. infrared camera detect the light invisible to human eye. This ‘thermal imaging’ is helpful for detecting people within the dark.
