<em>An electron has the same amount of energy in all orbitals is not true</em>
In an atom there are levels of energy in the skin and sub skin.
- This energy level is expressed in the form of electron configurations.
Writing electron configurations starts from the lowest to the highest sub-shell energy level.
So electrons that occupy the orbitals in the lowest sub-skin have the lowest energy level
- In the principle of Pauli's prohibition it was stated that there are no two electrons in one atom that can have the same four quantum numbers.
So suppose that there are two electrons occupying one orbital can have the same main quantum number (n), azimuth (l) and magnetic (m), then the last quantum number that is the quantum spin number (s) must be different.
So that the two electrons are different from just the quantum spin number, even though the other quantum numbers are the same.
So in one orbital only a maximum of 2 electrons is occupied, because if there is a third electron, this third electron will have the same quantum spin number as the previous electron
- The electron cloud is a visual representation of the location of electrons in an atom.
Orbital is the place around the nucleus where electrons may be found
Electron clouds show the state of electrons in their orbitals
So electron clouds can show the condition of all orbitals in an atom
The lowest energy level of an electron occupies a sub-skin of 1s which has only one orbital
Charging electrons in the sub skin uses the following sequence:
1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.

As the question is about changing in frequency of a wave for an observer who is moving relative to the wave source, the concept that should come to our minds is "Doppler's effect."
Now the general formula of the Doppler's effect is:
-- (A)
Note: We do not need to worry about the signs, as everything is moving towards each other. If something/somebody were moving away, we would have the negative sign. However, in this problem it is not the issue.
Where,
g = Speed of sound = 340m/s.
= Velocity of the receiver/observer relative to the medium = ?.
= Velocity of the source with respect to medium = 0 m/s.
= Frequency emitted from source = 400 Hz.
= Observed frequency = 408Hz.
Plug-in the above values in the equation (A), you would get:
Solving above would give you,
= 6.8 m/s
The correct answer = 6.8m/s
