Velocity of photon allways is c(photon is massless particle).While velocity of EM wave in medium < c.So does velocity of photon need not allways equal velocity of EM wave?
No. Photons and EM waves move at the same speed. They are the same thing.fxdung said:So velocity of photon is difference with classical EM wave(superposition of many photons)'s velocity?
No. THEY ARE THE SAME. It's just two different ways of modeling reality. The quantum approach (photons) is more accurate, but the classical approach (waves) is amazingly good (for something that's wrong) at solving large scale scale EM problems with easier math.fxdung said:But in medium speed of photon is c but speed of light is v<c?

The speed of light is a fundamental constant in physics, denoted by the letter c. In a vacuum, it has a precise value of 299,792,458 meters per second (m/s) or approximately 186,282 miles per second (mi/s).
The speed of light can be measured using various experimental methods, including the use of lasers, mirrors, and precise timing techniques. One of the most accurate methods involves using the time it takes for light to travel between two points, divided by the distance between those points.
Photons are particles of light that travel at the speed of light. This means that the speed of light is the maximum speed at which anything in the universe can travel, including photons. As photons have no mass, they are able to travel at this speed without any resistance.
The speed of light is incredibly fast, but it is not the fastest speed in the universe. The theory of relativity states that nothing can travel faster than the speed of light. However, there are some particles, such as neutrinos, that have been observed to travel at speeds very close to the speed of light.
No, the speed of light is a constant and cannot be changed. It is a fundamental property of the universe and is the same for all observers, regardless of their relative motion. However, the speed of light can be affected by the medium it is traveling through, causing it to slow down or change direction.
