Infrared waves
Infrared waves, also known as infrared radiation, are a part of the electromagnetic spectrum. They have longer wavelengths and lower frequencies than visible light. Their wavelengths range from about 700 nanometers to 1 millimeter.
Infrared waves are not visible to the human eye, but they can be detected as heat. Objects emit infrared radiation based on their temperature. The hotter an object, the more infrared radiation it emits.
Infrared waves have numerous applications in various fields. In heating applications, infrared heaters use infrared radiation to warm objects or people directly, rather than heating the surrounding air. Infrared therapy is also used in medicine for pain relief and to promote healing.
Infrared waves are widely used in remote controls, as they can transmit signals to electronic devices. They are also used in night-vision devices, security cameras, and thermal imaging cameras, enabling the detection of heat signatures and providing visibility in low-light environments.
Overall, infrared waves have applications in technology, communication, science, and medicine, making them an important part of our daily lives.
