According to theory of properties of photon, they can not be affected by electric and magnetic fields and it is neutral. But Electromagnetic waves contain electric and magnetic fields .
Which factor does not affect photon?
According to photon, they can not be affected by electric and magnetic fields . But EM waves are affected by external electric and magnetic fields.
What are the factors that affect the energy of a photon?
The energy of the photon depends on its frequency (how fast the electric field and magnetic field wiggle) . The higher the frequency, the more energy the photon has. Of course, a beam of light has many photons.
Which of the following does not affect the photon * 1 point magnetic or electric field light waves gravity current?
Which of the following does not affect the photon? Explanation: Photons have no charge . They can interact with charged particles but not with themselves. This is why photons are neutral and not affected by magnetic or electric fields.
Can photons be affected by magnetic fields?
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.
Which photon has the highest energy?
A collaboration of Chinese and Japanese astrophysicists has reported the highest energy photons ever seen: gamma rays with energies up to 450 trillion electron volts (TeV).
How many photons are in a light beam?
The energy of a single photon is: hν or = (h/2π)ω where h is Planck’s constant: 6.626 x 10-34 Joule-sec. One photon of visible light contains about 10-19 Joules (not much!) the number of photons per second in a beam.
Which has less energy per photon?
Radio waves have photons with the lowest energies. Microwaves have a little more energy than radio waves. Infrared has still more, followed by visible, ultraviolet, X-rays and gamma rays.
Do all photons have the same energy?
All photons possess the same amount of energy .
How many photons of radiation does a wavelength have?
As we need to find the number of photons falling in one second, ▽t=1 and so putting the value of p from equation (i) in the equation of force, we get F=nhλ and on rearranging terms, we will get ⟹n=Fλh=6.62×10−5×5×10−76.62×10−34= 5×1022 photons per second . Hence option b is the correct answer.
Why is photon zero rest mass?
From the particle nature of light, we consider light to travel in the form of small packets of energy or quanta of energy. These small packets are called photons. The photons are said to be chargeless and massless particles that travel at the speed of light . So the rest mass of a photon is taken to be zero.
Can a photon be deflected by an electric field?
Answer : Photon is a charge-less particle and hence it is deflected neither by an electric field nor by a magnetic field.
Which is not deflected by magnetic field?
Because they consist of charged particles, alpha and beta radiation can also be deflected by magnetic fields . Just as with electric fields, gamma radiation is not deflected by magnetic fields.
Does light interact with magnetic fields?
Light and magnetism do not interact . They ought to be able to interact, since light is electromagnetic radiation, and all such radiation consists of oscillating magnetic fields. ... “Photons, that is, particles of light, can be absorbed.
Why does a photon have no charge?
A photon is massless, has no electric charge , and is a stable particle. In a vacuum, a photon has two possible polarization states. The photon is the gauge boson for electromagnetism, and therefore all other quantum numbers of the photon (such as lepton number, baryon number, and flavour quantum numbers) are zero.
Is it possible to use the Earth’s magnetic field to produce electricity?
Spinning a coil of wire in a strong magnetic field
We do this by spinning a coil (containing many loops of wire) quickly in a strong magnetic field. During each turn of the coil, electrons get a kick from the magnetic field, moving them along. This creates electrical current.
