| It does feel a little odd that something the size of 5.29×10⁻¹¹ meter can create something 10 billion times larger. I mean, I understand how and why, but it feels odd. |

| My subwoofer is approximate cubic with 30 cm to a side. But the wavelength of sound it makes at 20Hz is approximately 17 meter. Wavelength is merely a human conceptualization. If we reconceptialize it as peak-to-peak interval it suddenly stops being length and becomes a time instead |

| ▲ | ttoinou 8 months ago | parent [-] | | The sound pressure wave does take 17 meters in the air to make a full cycle, no ? It’s real, same for the photon | | |

The fact that the first peak traveled some distance is irrelevant, as its entirely dependent on propagation speed, which doesn't affect the frequency, only vawelenght. | | |

| ▲ | ttoinou 8 months ago | parent | prev [-] | | Would you then say that the wavelength is meaningful for the sound example as its properties are really of a wave propagating, and meaningless for the light as the wave analogy isn’t a full description of the light phenomenon behavior ? | | |
| ▲ | MaxikCZ 8 months ago | parent [-] | | I have pretty strong intuition for how "sound looks". I know how to imagine a wavelength of sound, how the medium works over time etc. I don't have the same intuition about light, as the sound analogy of a wavelength (distance between 2 peaks) clash with the part of photon that behaves like a particle. From that standpoint I can confidently say that wavelength is meaningful for the sound example, but not so much for light. Someone more knowledgeable than me would probably offer better insight. |

| Wavelength isn't an object though. Like if you walk around the world you haven't made something the size of the world. |

| ▲ | nomel 8 months ago | parent | next [-] | | Wavelength is a time thing though. To make something that low frequency (1.4GHz or 7ps), things have to happen pretty slowly. | | | |
