photon vs electron speed

photon vs electron

why is photon speed more than electron speed?

 

[Old Nick]

speed of electron and photon

Electrons drift in an electric field - the electric field moves at the speed of light, the electrons don't.

photons versus electrons

Thats not quit right.Elektron like also photon has same speed in same medium:
For example in space vacum speed is same.

electron speed

You maybe right! But I'm not sure that the speed of photons has been measured in many of the types of media that electrons travel through! In silicon, a photon will only travel a few microns (depending on wavelength, red travells further than blue), before being absorbed and converted to an electron. I'm not sure the transmission of photons through copper wire has ever been quantified.
Beta radiation consists of electrons, but I'm not sure of the speed they travel in free space.

speed of electron

Hey

Physically, photon is a massless energy package that according to relativity theory would have the highest speed in a given medium (no matter what the medium is) with respect to any particle that has a defined mass (Ex. electron).

Hope it make sense

electron speed photon

Yess ghaidini but photon is also paritcal not just wave.
OK you give best answer.

speed of a photon relative to an electron

That's - excuse me - rubbish. In vacuum, e. g. in an electronic tube, you can have electrons with nearly zero speed, just forming a space charge. Seems as you don't know actually what you are talking about.

Dear,
According to quantum mechanics, all particles are waves also, but comon particles that we know them are just more localized than other waves. Thus photon and electron both are particles but photon is a massless particle.
