Is there a limit to the wavelength of light?
What is the visible light spectrum? More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.
Is there a maximum minimum energy of a single photon?
We have seen that the electromagnetic wave cannot have an arbitrarily small strength: it must have a minimum energy E which corresponds to one photon.
Is there an upper limit to wavelength?
There is no known absolute limit on the range of electromagnetic wavelengths, but most familiar forms of electromagnetic waves range from metres (radio) down to femtometres (gamma rays).
What is the maximum wavelength of light that would excite an electron?
The maximum wavelength of light that would excite an electron from energy level n = 1 to n =3 in atomic hydrogen is 102 nm.
How much energy can a photon hold?
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!)
What is maximum energy of photon?
High frequency Gamma rays photons have maximum energy compared to other photons in the electromagnetic spectrum. It is followed by X-rays, UV rays, Light waves, Infrared, Microwaves and Radio waves.
Is there a frequency limit?
There’s no atom in-between to vibrate the opposite direction. So there’s a maximum frequency, the Debye frequency, for any particular type of sound waves in any direction in a given crystal. That frequency varies a bit depending on direction and a lot depending on crystal type.
Can a photon have infinite wavelength?
There’s no specific limit for the wavelength of a Photon. Its wavelength can vary from approximately zero to near infinite. There isn’t any such limit.
What is the maximum wavelength of light capable of removing an electron?
The maximum wavelength of light that can remove an electron from a lithium atom is equal to 4.279⋅10−7m . So, you know that the work function of lithium, which is the energy needed to remove an electron from an atom located at the surface of the metal, is equal to 279.7 kJ/mol.
