What are Infrared Rays?
Infrared rays are a type of light that we cannot see with our eyes. They are part of the electromagnetic spectrum, which includes all types of light. While invisible to us, infrared rays have a longer wavelength than visible light but are shorter than microwaves. These rays are all around us, emitted by the sun, objects, and even our own bodies.
- They lie just beyond the red end of the visible light spectrum.
- Infrared rays have wavelengths between about 700 nanometers and 1 millimeter.
- We often feel infrared rays as heat, which is why the sun feels warm.
- All objects emit some infrared radiation, more so if they are hotter.
- A significant portion of the sun’s energy that reaches Earth is infrared.
- Although we cannot see them, infrared rays can be detected with special cameras and sensors.
Uses of Infrared Rays
Infrared rays are a type of invisible light. These rays have unique properties that set them apart from visible light. With longer wavelengths than the light we see, infrared rays interact with us primarily as heat. Despite being invisible, these rays have a significant impact on our daily lives. In this article, we will learn about the uses of infrared rays in daily life.
