What is the false statement regarding EM Waves?

The statement that electromagnetic (EM) waves cannot transmit information is false because EM waves are widely used for communication and information transfer. In fact, various forms of communication, such as radio, television, and wireless internet, rely on EM waves to convey data over distances. This capability is fundamental to many technologies that enable long-distance communication, demonstrating that EM waves are effective carriers of information.

Other statements about EM waves reflect accurate characteristics. For instance, they can indeed have very short wavelengths, which are common in gamma rays and X-rays. Some EM waves, like gamma rays, can possess wavelengths shorter than atomic dimensions, affirming the statement regarding their potential to be shorter than the width of an atom. Furthermore, EM waves are classified across a spectrum of frequencies, from low-frequency radio waves to high-frequency gamma rays, illustrating their existence in different frequency ranges.
