Description of Infrared Waves

Infrared waves are a type of electromagnetic radiation of a wavelength or color of a certain thing. They are also use to detect visible light waves or radiation such as humans and animals and things that are warm or hot.

The wavelength range of a Infrared wave is about 30 cm to 740 nanometers (nm). The frequency is about 3 GHz up to about 400 THz, but these values are not definitive.

The velocity in a vacuum is about 300,000,000 meters/second.

Key facts: Infrared light is only produced on to things that are hot enough to detect, if not then it would not be able to work.

Everyday Applications.

Health Impacts

Infrared radiation can be dangerous to humans. It can cause eye and skin damage. It can cause a sun burn.

Positive impacts is when someone is suffering from chronic pain, headache due to blood vessel problems.

This article explains what infrared waves are and how it was discovered and the wave length and frequency and how it also being used.

Infrared waves is a type of electromagnetic radiation as a radio wave x-ray, ultraviolet radiation. IR radiation is one out of the 3 ways heat is transferred from one place to another. Electromagnetic radiation is transmitted in different wavelengths and frequencies. William Herschel the person who discovered Infrared waves, According to NASA it was found in the 1800's.

Infra-red radiation
In this video she explains how infrared is used and how to define it on things. Like if it lighter that means that the person or object is warm or hot, and if its cold than the object is cold.
