What is infrared light and how is it used?

Infrared light is a type of electromagnetic radiation with wavelengths longer than visible light. It's used in various applications like remote controls, thermal imaging, and night vision.

Can you explain how thermal imaging works?

Thermal imaging detects infrared radiation emitted by objects, converting it into an image. It allows us to see heat patterns, useful in fields like firefighting and building inspections.

What are some everyday devices that use infrared technology?

Common devices include TV remote controls, infrared saunas, and certain types of cameras that capture heat signatures.

Is infrared light safe for human exposure?

Yes, infrared light is generally safe for human exposure, but prolonged exposure to high levels can cause skin burns.

How does infrared light differ from ultraviolet light?

Infrared light has longer wavelengths than ultraviolet light and is primarily associated with heat, while ultraviolet light can cause skin damage.
