I WONDER - What Are Radio Waves?

The video tutorial explains that radio waves are a form of radiation, which is energy in motion. It introduces the concept of frequency, defined as the number of waves passing a point per second. The tutorial also describes how transmitters convert audio and visual content into electric signals, which are then combined with radio waves of specific frequencies for transmission.
