Questions & Answers

Q: How does an infrared camera work and what can it detect?

An infrared camera converts invisible infrared light into visible colors, helping us see temperature differences. It can detect hotspots, cold areas, and even reveal hidden objects based on their temperature radiation.

Q: Why is infrared often associated with detecting heat?

Infrared light is emitted by objects based on their temperature. Hot objects emit more infrared light, while cooler objects emit less. Therefore, infrared cameras can detect temperature variations and are often associated with detecting heat.

Q: How does infrared light differ from visible light?

Infrared light has lower energy than visible light and is not visible to the human eye. However, it can be detected by special cameras and reveals temperature differences that are not visible in the visible light spectrum.

Q: What are some practical applications of infrared cameras?

Infrared cameras are used for various purposes, such as identifying energy losses in buildings, detecting moisture and pests in walls, and even capturing thermal images in military or surveillance operations.
