- 1Infrared radiation can strongly ionize atoms, revealing hidden electromagnetic signatures.
- 2Infrared waves are completely unabsorbed by atmospheric gases and are ideal for deep-space interstellar communication.
- 3All objects emit infrared radiation proportional to their temperature, making it ideal for heat-based detection.✓
- 4Infrared waves have higher energy and pass through solid obstacles better than visible light.
Correct answer
All objects emit infrared radiation proportional to their temperature, making it ideal for heat-based detection.
