Wavelength and Frequency

The wavelength of infrared rays range from 7 millimeters to 750 nanometers

The frequency ranges from 4 X 10 14 Hertz to 1 X 10 13 Hertz

The Electromagnetic Spectrum

Infrared rays fit between microwaves and visible light.

sir william herschel discovered infrared rays
Sir William Herschel Discovered Infrared Rays

Discovered in 1800, the German astronomer split light using a prism (an object that can split white light into a spectrum/rainbow) and used a thermometer to find out whether heat was being emitted without light.

Herschel concluded that there must be invisible heat rays, and his hypothesis was correct.
