Grahame- You’re right that electromagnetic waves, whether viewed classically or in terms of quantized photons, are not affected by static electrical or magnetic fields. They have no charge. … Photons are little units of light — they are the original “quanta” of quantum mechanics.
Which is not affected by electric field?
Gamma ray is electromagnetic wave which is neutral. So gamma ray is not affected by electric and magnetic field.
Do electric fields affect light?
Not normally. Electric and magnetic fields only directly act on electrical charge, and light has no electrical charge. However, in the case of extremely strong electric fields, quantum effects can cause the scattering of photons: Delbrück scattering .
Are photons affected by magnetic field?
Although a magnetic field doesn’t affect the photons of light directly, a magnet can distort the medium through which light passes and thereby “bend” the light rays. … A strong magnetic field can increase the effect of the mass of the object on the curvature of space-time.
Is electromagnetic field made of photons?
Electromagnetic fields are made out of photons. The magnitude and direction of the electromagnetic field intensity at any point is directly proportional to the magnitude and direction of the force of the photon at that point.
Is Proton is deflected by electric field?
Behavior of protons, neutrons and electrons in electric fields. … Protons are positively charged and are thus deflected on a curving path towards the negative plate.
Do magnetic fields affect electromagnetic waves?
EM waves are basically vibrating electric and magnetic fields. So it seems that em waves should be deflected by Electric or magnetic fields .
Is it possible to use the Earth’s magnetic field to produce electricity?
Actually, it’s possible to use the Earth’s magnetic field to generate electricity. A satellite in the form of large diameter loop in orbit around the Earth will generate a current in that loop, and could be used to power something, but at the cost of a rapidly degrading orbit.
How electric forces and electric fields interact in lighting?
In the world of electricity, opposites attract and insulators inhibit. As positive and negative charges begin to separate within the cloud, an electric field is generated between its top and base. … This positive charge will shadow the storm wherever it goes, and is responsible for cloud-to-ground lightning.
Does a stationary charge produce electric field?
A stationary charge will produce only an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced. An electric field can be produced also by a changing magnetic field.
Do photons carry energy?
Light indeed carries energy via its momentum despite having no mass. … Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum.
Are photons affected by gravity?
Photons, whether they are particles or waves seem not to interact with this field at all acording to their speed, however they are still affected by gravity.
Are Lasers affected by magnetic fields?
The laser intensity decrease observed at large magnetic fields in the computation that excludes the Zeeman effect is the result of a smaller gain caused by a decrease in the density, reduced transient effects associated with ionization and excitation, and an increase in the optical depth.
Why does a photon have no mass?
The answer is then definitely “no”: the photon is a massless particle. … Even before it was known that light is composed of photons, it was known that light carries momentum and will exert pressure on a surface. This is not evidence that it has mass since momentum can exist without mass.
Do magnetic fields have mass?
magnetic fields are produced by charged particles in motion, and depend on the charge and velocity of these particles, but not on their mass.
What does a photon look like?
A photon just looks like a blink of light from a small point. So, when you see a photon (if your eyes are sensitive enough), you see a blip of light. The “size” of a photon is much weirder since photons aren’t “particles” in the traditional macroscopic sense of the word.
