The discussion centers on the relationship between photons and electromagnetic waves, asserting that photons are the fundamental units of electromagnetic radiation. It clarifies that when transmitting antennas emit energy, they do so in the form of photons, which can be detected by receiving antennas. The conversation emphasizes that there is no electromagnetic wave without photons, as they represent discrete energy deliveries. Furthermore, it highlights that while photons can be detected individually, measurements may also capture the total energy from many photons arriving simultaneously. Ultimately, photons and electromagnetic waves are interconnected, with photons serving as the basic constituents of light.
