What is the energy of a photon at wavelength of 620 nm?
2 eV
Energy of photon (eV) = 1240 eV-nm/(wavelength in nm). For example, orange light with a wavelength of 620 nm corresponds to photons carrying 1240 eV-nm/620 nm = 2 eV.
What is the energy of a 600 nm wavelength photon?
The enegy of photon corresponding to a radiatio of wavelength 600 nm is `3.32xx10^(-19)J`.

What is the energy of 600 nm?
=3.3×10-19J.
What is the energy of a photon of wavelength lambda?
The energy of a photon of wavelength lambda is [ h = Planck’s constant, c = speed of light in vacuum ] For the photon, E=hv=hcλ.
What is the wavelength of radiation having frequency 1000 hertz?
=3×105m=3×107cm.
What is the energy in J of a 635 nm photon?
The answer is 3.54×10−19 J .
What is the energy of a photon with a wavelength of 665 nm?
Question: Electromagnetic radiation with a wavelength of 665 nm appears as orange light to the human eye. The energy of one photon of this light is 2.99 × 10-19 J.
How is the energy of a photon related to its wavelength?
The energy of light (or photon energy), E, is inversely proportional to the wavelength by the equation: where h is Planck’s constant (6.6261 x 10 -34 J*s) and c is the speed of light (2.9979 x 10 8 m/s).
Which is the frequency of a photon F?
f is the frequency of a photon. This equation gives us an energy of a single, indivisible, quanta of light and we can think of light as a collection of particles. The opposite is also true. We can think about ordinary particles, like electrons, as waves.
How is the rate of photon energy transfer calculated?
The International System of Quantities (SI) have defined 1 eV to the exact value of 1.602 176 634 ×10−19 J. Thus, equation 1 above can be rewritten for photon energy in eV and wavelength in nm as: Power (P) is the rate of energy transfer with the SI unit of 1 Watt = 1 J/s.
The power of short wavelength light sources in the EUV to X-ray range are often expressed as photon flux ( F) in the units of photons per second (ph/s). Average power is related to flux and photon energy by: For any given flux and wavelength (in nm), equation 5 can be used to calculate the corresponding average power (in m W).
