Do individual photons have some attributes which relate to EM wave frequency? In other words, is there any difference in photons composing a red and blue beam of light?
Matterwave said:Certainly, photons composing blue light have a higher frequency which means they have a higher momentum, and a higher energy.
humbleteleskop said:I didn't think frequency could be attributed to individual photons.
How do we differentiate 1,000 photons each having energy E, from 2,000 photons having energy E/2? What would be the instrument or type of sensor that could tell that difference?
humbleteleskop said:Interesting. Especially the part how neither amplitude nor wavelength are responsible for the effect, but frequency alone. Which doesn't really make sense to me as I understand all three are proportionally correlated, so I don't see how frequency can be independent of the other two in such way.
Jilang said:Yes, I always thought that the wavelength was c/f. I don't think a single photon had an amplitude though.
Photons are the fundamental particles that make up electromagnetic waves. The energy of a photon is directly proportional to the frequency of the EM wave. This means that as the frequency of an EM wave increases, so does the energy of the photons making up the wave.
The frequency of an EM wave determines its properties, such as wavelength, energy, and polarization. Higher frequency waves have shorter wavelengths, higher energy, and are more likely to be polarized. Lower frequency waves have longer wavelengths, lower energy, and are less likely to be polarized.
No, photons cannot exist without an EM wave. They are the carriers of electromagnetic energy and are always associated with an EM wave. Without an EM wave, there would be no photons.
The electromagnetic spectrum is a range of all possible frequencies of EM waves, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each of these types of waves consists of photons with different frequencies, energies, and properties. The electromagnetic spectrum shows the relationship between photons and EM wave frequency.
The relationship between photons and EM wave frequency has a significant impact on technology. Different frequencies of EM waves allow us to use different technologies, such as radio communication, X-ray imaging, and infrared cameras. The ability to manipulate and harness the frequency of EM waves has led to advancements in various fields, including telecommunications, medicine, and astronomy.
