Question

according to the thermal image, which part of the room emits the highest - energy infrared waves?
the radiators under the windows
the windows and their frames
the walls around the windows

Explanation:

The energy of infrared waves is related to temperature. Higher - temperature objects emit higher - energy infrared waves. In the thermal image, the color scale shows that the warmest (highest - temperature) areas correspond to the radiators under the windows (as they are shown in the warmest colors like red - orange in the thermal image which is associated with higher temperatures on the color scale \(8^{\circ}C - 41^{\circ}C\)).

Answer:

the radiators under the windows
