Answer : The wavelength of photon would be absorbed,
Explanation :
From the given diagram of energy we conclude that,
Energy at ground state, A = 400 zJ
Energy of 2nd excited state, C = 1050 zJ
Now we have to calculate the energy of the photon.
Now we have to calculate the wavelength of the photon.
Formula used :
As,
So,
where,
E = energy of photon =
= frequency of photon
h = Planck's constant =
= wavelength of photon = ?
c = speed of light =
Now put all the given values in the above formula, we get:
Therefore, the wavelength of photon would be absorbed,
