Answer : The magnitude of the orbital angular momentum for its most energetic electron is,
Explanation :
The formula used for orbital angular momentum is:
where,
L = orbital angular momentum
l = Azimuthal quantum number
As we are given the electronic configuration of Fe is,
Its most energetic electron will be for 3d electrons.
The value of azimuthal quantum number(l) of d orbital is, 2
That means, l = 2
Now put all the given values in the above formula, we get:
Therefore, the magnitude of the orbital angular momentum for its most energetic electron is,
The frequency of the re-emitted light is identical to that of the absorbed light.
To find the answer, we need to know more about the frequency of light.
<h3> Why the re-emitted light has the same frequency?</h3>- The wavelength of the light that is momentarily absorbed in glass and then re-emitted is the same, which explains why the re-emitted light has the same frequency as the absorbed light and the frequency of the absorbed light is the same.
- An electromagnetic wave's energy is inversely related to its frequency.
- The relationship between the wave's wavelength and frequency depends on the speed of light:
, c is the speed of light.
- Despite not having mass, light still has energy, and that energy is conserved.
- As a result, in order for there to be energy conservation, the energy of the light that is received and reemitted must be equal.
Thus, we can conclude that, the re-emitted light's frequency matches the absorbed light's frequency.
