B. The inverse.
The energy of a photon is:
E = hf
Where h is a constant (planck's) and f is the frequency of light. We also know that the frequency of light is:
f = c/lambda
Where c is a constant (speed of light) and lambda is the wavelength. Substituting:
E = hc/lambda
From this equation we see that it is inversely proportional.

E = hf; where h = Plank's constant and f = frequency of the photon in number of cycles per second. Also, L = ct; where L is the wave length, c is the speed of light, and t is time. Thus, t = L/c is the time to travel one cycle of the wave length L.
f = 1/t = c/L when L = one wave length. Therefore E = hf = h(1/t) = hc/L in which case the energy E is inversely proportional to the wavelength L. That is, shorter wave lengths give us higher energy photons.

The energy of a photon is proportional to its frequency. Frequency is inversely proportional to wavelength. Therefore, the energy of the a photon is inversely proportional to its wavelength.
E = hv
where E = energy, h = Planck's constant, v = frequency

The artwork function potential WE is the quantity of binding potential the photon could conquer to knock an electron out of its orbital. So, theoretically, if the potential of the photon TE = hf = WE, all its potential could be expended getting the electron far off from its atom. yet there could be none left over for the electron to have kinetic potential. on condition that TE > WE, so as that TE - WE = KE > 0 is there sufficient left over potential from the photon's potential to propel the electron and supply it kinetic potential. The conservation of potential is yet differently to look at it. whilst the great potential enter is that of the photon we've TE = WE + KE the place this RHS is the artwork and kinetic energies, which, with the aid of conservation regulation, could upload as much as the great potential enter by skill of the photon.

The energy of a photon of light is given by the equation E=hc/wavelength. Thus, an increase in wavelength will produce a decrease in Energy. b is correct.

Shorter wavelengths have more energy per photon.
