What is the frequency range of infrared radiation?


Sagot :

Answer:

300 GHz to 400 THz

Explanation:

Infrared radiation (IR radiation for short) describes electromagnetic waves in the spectral range between visible red light and longer-wave microwave radiation (also known as terahertz radiation). Infrared (IR) has wavelengths λ between 780 nm and 1 mm, which corresponds to a frequency range from 300 GHz to 400 THz.
