Question

infrared waves have many different applications. select the true statements.
infrared satellite images can be used to monitor land after a forest fire.
stars born in dust clouds are visualized using infrared light.
infrared waves are used to see objects on land or in space that are not easily seen with visible light.

Explanation:

1. Infrared satellite images detect heat signatures, making them effective at monitoring remaining hot spots and damage after forest fires, so this statement is true.
2. Infrared light can penetrate dense dust clouds that block visible light, allowing astronomers to visualize stars forming inside these clouds, so this statement is true.
3. Infrared waves detect thermal radiation, enabling observation of objects (like cool space objects or heat-emitting land targets) that do not emit or are obscured from visible light view, so this statement is true.

Answer:

• Infrared satellite images can be used to monitor land after a forest fire.
• Stars born in dust clouds are visualized using infrared light.
• Infrared waves are used to see objects on land or in space that are not easily seen with visible light.
