The magnitude of the charge on a photon is 4/3 atto Coulombs, 1.33E-18 Coulombs.
photon
The photon IS the particle in this case. It isn't known to be made up of any smaller particles. The electric charge of a photon is zero.
No. Both the photon and the neutrino have zero electrical charge and as such cannot create a charged particle.
Well one way to look at it is that a photon IS an electromagnetic field. The photon is the gauge particle for the electromagnetic force. Without photons there would be no electromagnetic interaction force, and therefore no electromagnetic fields.
The high energy photon that results from the redistribution of the charge within the nucleus is called a gamma ray. It refers to a penetrating electromagnetic radiation that arises from the radioactive decay of atomic nuclei.
The electric charges of the proton and electron are equal in magnitude (size, strength), and opposite in sign.
A photon has zero electrical charge.
No. Otherwise it wouldn't be a photon.
photon
Assuming the photon is reflected into the same medium it came from (so we can ignore refraction), its momentum differs only directionally, its magnitude stays the same. The directional component of its momentum vector is always pointing in the direction it's propagating. Refraction is the means by which the magnitude component of the vector changes. The change in momentum of photon is nh/lambda.
Electric field is dependent on the magnitude of the electric charge, E = qzc/r2
The photon IS the particle in this case. It isn't known to be made up of any smaller particles. The electric charge of a photon is zero.
They are equal in magnitude but opposite in charge.
They are equal in magnitude but opposite in charge.
No. Both the photon and the neutrino have zero electrical charge and as such cannot create a charged particle.
No, they aren't. Photons are the gauge particles of the electromagnetic force, but they themselves carry no electric charge (or magnetic charge either, for that matter). A photon has no electrostatic charge.
brightness and temperature are both related because brightness is actually tempature. However the system has become more refined. Instead of just looking at the star and determining magnitude one or magnitude two, an astronomer measures the brightness of the star using a device called a photometer. The photometer counts the number of photons coming from the star. This photon count is then compared to the photon count from a star whose magnitude is known. An accurate magnitude can then be calculated.
