Quantum mechanics Quote by Richard P. Feynman
““No phenomenon directly involving a frequency has yet been detected above approximately 10^12 cycles per second. We only deduce the higher frequencies from the energy of the particles, by a rule which assumes that the particle-wave idea of quantum mechanics is valid.””
About This Quote
Source Lecture: The Theory of Quantum Electrodynamics, 1965
Higher frequency electromagnetic phenomena above 10^12 Hz are inferred indirectly via particle energy, assuming quantum wave‑particle duality.
In simple terms: We detect ultra‑high frequencies by their effects, not directly.
Key Takeaway
Rely on indirect measurements for extreme frequencies.

![“If I say [electrons] behave like particles I give the wrong impression; also if I say they behave like waves. They behave in their own inimitable way, which technically could be called a quantum mechanical way. They behave in a way that is like nothing that you have seen before.” quote by Richard P.
