@paulnord You saw all the video and you comment about this?
-
I think about stuff like this all the time, but I guess some people don't.
-
@paulnord I think by "slower" he meant lower frequency.
-
@paulnord He said water waves were

@paulnord not sure if trolling
-
Did he really say that long waves travel slower?
Sorry Feynman, there is no dispersion for EM waves in air/vacuum.

@JayGatsbyOdysseus Sound is just air vibrating in such a way that your ears find meaningful. There are no particles involved except the molecules in the air that are vibrating.
Light is of an entirely different nature. In some ways it behaves as it would if it were a particle, but then you study it some more and find out that it behaves as it would if it were a wave. In fact, as you said it is both.
How can this be? It's the nature of it. The inconceivable nature of nature!

Light is an electromagnetic wave. However, it is also a particle, a photon. Physicist can explain how it is both but it is. Is sound also a wave and a soundton?
