Question

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

Explanation:

Step1: Recall the relationship between temperature and infrared energy

According to Planck's law, the energy of infrared waves is related to the temperature of the object (higher - temperature objects emit higher - energy infrared waves).

Step2: Analyze the thermal - image color - temperature scale

The thermal - image color - temperature scale shows that lower temperatures (e.g., \(8^{\circ}C - 13^{\circ}C\), represented by blue) correspond to lower - energy infrared emissions.

Step3: Identify the object in the image with the lowest - temperature color

In the thermal image, the windows and their frames (shown in blue on the thermal - imaging device) have the lowest temperature among the given options.

Answer:

the windows and their frames
