Radio waves are not tangible matter in the traditional sense. They are a form of electromagnetic radiation, which is a type of energy that can propagate through space without the need for a medium. Unlike physical matter, radio waves do not consist of particles or substances that you can touch or feel.
Instead, radio waves are characterized by their wavelength, amplitude, and frequency. Wavelength refers to the distance between successive peaks or troughs of the wave, amplitude represents the strength or intensity of the wave, and frequency refers to the number of wave cycles occurring per unit of time.
Electromagnetic radiation, including radio waves, is classified as a type of energy rather than matter. It is composed of electric and magnetic fields oscillating at right angles to each other and perpendicular to the direction of wave propagation.
So, while radio waves possess measurable properties such as wavelength, amplitude, and frequency, they are not tangible matter but rather a form of energy that can be used for communication and various other purposes.
