phonons
Произношение: [ˈfoʊnɒnz]
Слово
Контекст: «physics»
(noun) a phonon is a tiny packet of sound energy in a solid. It helps us understand how sound travels in materials just like little balls bouncing around. When you pluck a guitar string, phonons are created and move through the guitar body, helping to create the music you hear.
Пример
When the guitar was played, it produced phonons that traveled through the air and made beautiful music.
Пример
Even though it was loud, there were no phonons traveling through the air in the empty room.
Пример
What happens to the phonons when the temperature of the solid increases?
Контекст: «quantum mechanics»
(noun) in the world of tiny particles, a phonon is a way to describe how particles called atoms store and move sound energy. It's like having tiny messengers that carry information about sound from one place to another at the smallest level.
Пример
Scientists study phonons to learn how heat and sound work at the quantum level.
Пример
The experiment did not show any phonons moving because it was too cold to generate sound energy.
Пример
Why are phonons important in understanding how materials conduct heat?
