We use the Planck relation,
E=hν,
where h=Planck's constant=6.626070040(81)×10^−34 J⋅s
Explanation:
Thus
E=6.626070040(81)×10−34J⋅s×6.42×10^14⋅s^−1≅10^−20 J.
Therefore, energy of a photon ≅ 10^−20 J.
E = h * f
h = Planck's constant = 6.62608*10-34 (J.s)
f = frequency (s-1) = 6.5*1014 Hz
multiplying gives the answer in Joules = 4.3*10-19J (per elementary particle)
(Explanation): multiply frequency by Planck's constant, 6.626 x 10 ^(-34) to get your answer.

The energy is 3,6112.10e-19 joule.
The energy of the photon is the same as the energy lost by the electron
Yes. The energy is given by plank's constant times the frequencie of the photon (remember that light is both particle and wave). So since blue light has higher frequency than green light, it is more energetic.
it looses energy , it gives off light in the form of a single photon.
The energy in one photon of any electromagnetic radiation is directly proportionalto its frequency, so that would be inversely proportional to its wavelength.Note: There is no energy in the protons of light, since light has no protons.

The amount of energy in a photon of light is proportional to the frequency of the corresponding light wave.... frequency of the electromagnetic radiation of which the photon is a particle.
The energy is 2,9619.e-19 J.
The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.
You need to know the photon's frequency or wavelength. If you know the wavelength, divide the speed of light by the photon's wavelength to find the frequency. Once you have the photon's frequency, multiply that by Planck's Konstant. The product is the photon's energy.
In the case of linear optical transitions, an electron absorbs a photon from the incoming light and makes a transition to the next higher unoccupied allowed state. When this electron relaxes it emits a photon of frequency less than or equal to the frequency of the incident light (Figure 1.3a). SHG on the other hand is a two-photon process where this excited electron absorbs another photon of same frequency and makes a transition to reach another allowed state at higher energy. This electron when falling back to its original 39 state emits a photon of a frequency which is two times that of the incident light (Figure 1.3b). This results in the frequency doubling in the output.
A particle of light. Or, in general, of an electromagnetic wave.
The energy per photon is directly proportional to the frequency; the frequency is inversely proportional to the wavelength (since frequency x wavelength = speed of light, which is constant); thus, the energy per photon is inversely proportional to the wavelength.
