Question

what is the phonons tell me zara​

Answer 1

Ur answer ^_^

RigHt.......

◼◼A quantum of energy or a quasiparticle associated with a compressional wave such as sound or a vibration of a crystal latice!◼◼

Hope it helps Uhhhhhh ✨✨✨✨

Answer 2

A phonon is a collective excitation in a periodic, elastic arrangement of atoms or molecules in a condensed matter, specifically in solids and some liquids.

Explanation:

• The quantization of energy of waves in acoustic mode is done by phonons.

• The phonons travel with a velocity of sound in a solid medium.

• The vibrational frequency of phonon varies in a wide range.

• Phonons can be increased by increasing the temperature in the solid.

• Main Part of energy of the phonon is the thermal energy of the solid.

• Phonons are indistinguishable particles are similar to photons.

• So, Bose-Einstein distribution can be used to describe their distribution in solid.

• The momentum of the photon is also called crystal momentum.
