Infrared light is invisible to the human eye. We can't see it because its wavelengths are longer than those of visible light.
While we can't see infrared light, we can feel it as heat. This is because infrared radiation carries energy that can be absorbed by objects, causing them to warm up.
Here are some examples of how infrared is used in everyday life:
- Remote controls: Many remote controls use infrared light to communicate with devices like televisions and stereos.
- Night vision: Night vision devices use infrared light to see in low-light conditions.
- Thermal imaging: Thermal imaging cameras detect infrared radiation emitted by objects, allowing us to see their temperature differences.
Infrared light is a fascinating part of the electromagnetic spectrum, playing a crucial role in various technologies and scientific applications.
