I read in a book that: Microwaves are considered lower in energy than infrared waves because they do not affect all molecules, only the polar ones. Polar molecules have slightly different electrical charges at their opposite ends, making them more responsive to microwave radiation than nonpolar molecules. Infrared heat, on the other hand, increases the vibration of nearly all molecules. Isn't it true that Microwaves are higher in energy than infrared waves because they contain shorter wavelengths? Isn't it true that compared to Infrared radiation, Visible light radiation, UV-Rays, Microwaves, X-Rays, and Gamma rays are all more energetic? Why do microwaves, according to this book, only affect polar molecules? If anyone can provide for me an explanation that can be applied universally, I would be grateful. Thanks in advance!
