Answer 2

Photon

In modern physics, the photon is the elementary particle responsible for electromagnetic phenomena. It mediates electromagnetic interactions and makes up all forms of light. The photon has zero invariant mass and travels at the constant speed c, the speed of light in empty space. However, in the presence of matter, a photon can be slowed or even absorbed, transferring energy and momentum proportional to its frequency. Like all quanta, the photon has both wave and particle properties; it exhibits wave–particle duality.


Phonon

In physics, a phonon is a quantized mode of vibration occurring in a rigid crystal lattice, such as the atomic lattice of a solid. The study of phonons is an important part of solid state physics, because phonons play a major role in many of the physical properties of solids, including a material's thermal and electrical conductivities. In particular, the properties of long-wavelength phonons give rise to sound in solids -- hence the name phonon, i.e., voice in Greek. In insulating solids, phonons are also the primary mechanism by which heat conduction takes place.

Phonons are a quantum mechanical version of a special type of vibrational motion, known as normal modes in classical mechanics, in which each part of a lattice oscillates with the same frequency. These normal modes are important because, according to a well-known result in classical mechanics, any arbitrary vibrational motion of a lattice can be considered as a superposition of normal modes with various frequencies; in this sense, the normal modes are the elementary vibrations of the lattice. Although normal modes are wave-like phenomena in classical mechanics, they acquire certain particle-like properties when the lattice is analysed using quantum mechanics (see wave-particle duality.) They are then known as phonons. Phonons are bosons possessing zero spin.

Answer 3

in basic terms get the only you're comfortable driving and the only which you will take care of to pay for. you may continually get some thing else later. :-) I desire a Harley yet I grew up with Honda and Yamaha. i like, love, love the way that the HD's sound and look of direction. they're in basic terms fascinating motorcycles. My bf has a Harley and that i like driving on each occasion we are able to. I continually rearrange my artwork time table each spring and summer season so we are able to holiday as much as available. even although, i does no longer no longer date a guy because of the fact he owned some thing different than a Harley. I probable does no longer holiday as lots if he owned a crotch rocket because of the fact it quite is way uncomfortable for me to be a passenger rather while it quite is warm exterior. solid luck

Answer 4

It is absolutely different things

Photon comes from light

phonon comes from sound
