Answer:
a) D
b) C
c) B
d)E
e)A
Step-by-step explanation:
For clarity, I have attached the images of the transitions to aid understanding.
The visible spectrum consists of Red, Orange, Orange,Yellow Green, Blue,Indigo,Violet. The magnitude of the wavelength of each decreases from left to right in that order. This implies that the red portion of the spectrum is less energetic than the violet portion because energy of a photon increases with decreasing wavelength.
D corresponds to the violet region because the energy difference between the two energy levels is high and requires the absorption of short wavelength, high energy photons of light.
In (b), image C represents an emission that involves a shorter wavelength and can only correspond to blue since it is from a energy level n=3 to n=1
In image (c) , green light is intermediate in energy and will correspond to image B because image F reflects a transition that occurs at a longer wavelength since the energy levels are close together.
In (d) orange light is found at the far, long wavelength portion of the spectrum hence it may involve an n=4 to n=2 transition.
A represents the ionization of the atom, the electron is finally lost from the atom.
