Does light have a possible shortest limit of wavelength and a possible longest limit of wavelength?
When the wavelength of light becomes very very short, i.e., infinitely short, or infinitely long, will there be problem for the light phonon?
Is there any recorded shortest wavelength and longest wavelength of light?
Thanks a lot.
The minimum theoretical limit is the Planck Leght. above this lenght, there is no theoretical limit.
And the maximum theoretical limit of the Wavelenght for light would be the size of the Observable Universe. Again, there is no maximum theoretical limit for this, below the size of the Observable Universe (aprox. 93 billion light years in lenght)
To the best of my knowledge, there is no upper limit for the wavelength.
The Planck length does not place a lower bound on the wavelength of light. See, for example, the Wikipedia article on Planck length.
Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. Ultraviolet (UV) light—is radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400 .
Order is as follows (shortest to longest wavelength): Gamma, X-Rays, UV, Visible, Infrared, Microwaves, Radio Waves. Gamma has the shortest wavelength because it has a higher frequency, meaning more waves in a second than any other radiation, which results in the short wavelength.
In electromagnetic theory, the frequency spectrum (of vibrating photons) extends from 0Hz to infinity. However, infinite frequency means photons with infinite energy and we don't know such a source of radiation in nature. Also, the photons with zero energy means they are coming from infinite distance and our radio telescopes did not (and cannot) detect such radiations (at 0K). In conclusion, the maximum and minimum wavelengths are limited by the most energetic source of radiation in nature and the size of the observable universe itself.
