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. ... As the frequency of a photon goes up, the wavelength () goes down, and as the frequency goes down, the wavelength increases.
Which has more energy a photon of?
The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays .
Which of the following will increase 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. ... As the frequency of a photon goes up, the wavelength () goes down, and as the frequency goes down, the wavelength increases.
Does speed increase with increasing photon energy?
The energy of a photon is not related to its speed because photons are massless. Increasing the energy of a photon will increase its momentum however . The momentum of a photon is equal to Planck’s constant divided by the wavelength of a the photon.
What does the energy of a photon depends on?
The energy of a photon depends on radiation frequency ; there are photons of all energies from high-energy gamma- and X-rays, through visible light, to low-energy infrared and radio waves. All photons travel at the speed of light.
How does a photon lose energy?
A photon doesn’t lose energy unless it collides with a particle . Photons can scatter off interstellar electrons, for example. (Perhaps you were thinking about particles, like electrons, losing energy “in transit” in a vacuum. ... Photons carry energy, but they don’t lose energy just because they travel.
Which factor does not affect the 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.
Which radiations has the strongest photon?
A gamma ray (g) is a packet of electromagnetic energy (photon) emitted by the nucleus of some radionuclides following radioactive decay. Gamma photons are the most energetic photons in the electromagnetic spectrum.
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.
What is the greatest energy?
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.
Does photon have same energy?
Photons of different frequencies have different lengths between every full oscillation. The different “bubbles” are of different diameter dependent from their frequency and by this of different energy. Does all the photons have the same energy? Definitely not.
Which photon is more energetic red or green?
, that is, energy of a photon is inversely proportional to the light’s wavelength. – Hence, the light having the lowest wavelength will have maximum energy. – On the basis of wavelength, red has the maximum wavelength, then green, then comes blue and lastly violet. Therefore, violet has the maximum energy.
Is all photons have same energy?
All photons possess the same amount of energy .
What is the energy of a 500 nm photon?
The energy of a 500 nm photon is 4 x 10−19 J .
Is velocity of photon depends on its wavelength?
Example: For a constant frequency, when the velocity of the photon is doubled the wavelength also gets doubled. Thus, the velocity of a photon is dependent on the wavelength .
Where do photons get their energy?
Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum . Now there is an interesting additional effect contained in the general equation.
