The Correct Option is C

Solution and Explanation

As the wavelength of infrared radiation extends from $ 8000\times {{10}^{-10}}m $ to $ 400000\times {{10}^{-10}}m. $ These radiations have longer wavelength and these can penetrate deeply into materials, causing heating effect.

Electromagnetic Spectrum

The term used by scientists to describe the entire range of light that exists is the electrostatic spectrum. Light is a wave of alternating electric and magnetic fields. The propagation of light doesn't vary from waves crossing an ocean. Like any other wave, light also has a few fundamental properties that describe it. One is its frequency. The frequency is measured in Hz, which counts the number of waves that pass by a point in one second. 

The electromagnetic waves that your eyes detect are visible light and oscillate between 400 and 790 terahertz (THz). That’s several hundred trillion times a second.
