Longer wavelength radiation is of lower strength and is normally abrupt harmful patterns add radio, microwaves and infrared.infrared, is a range of the electromagnetic radiation spectrum where wavelengths vary from about 700 nanometers (nm) to 1 millimeter (mm). Infrared waves are normally larger than those of visible light but these are basically shorter than those of radio waves.
The Earth gets hotter as one travels towards the core, known as the geothermal gradient. The geothermal gradient is the amount that the Earth's temperature increases with depth.
