Answer:
C. n = 6 → n = 2 Violet
D. n = 5 → n = 2 Blue
A. n = 4 → n = 2 Green
B. n = 3 → n = 2 Red
Explanation:
The transitions involved are all to energy level n=2 from higher energy levels. The energy of the emission line correspondingly will reflect a higher energy the greater n is and the color of the emission spectra line will likewise correspond to higher energy. Since the energy of the colors given follow the sequence:
<h3>
Eviolet ⇒ E blue ⇒ Egreen ⇒ E red</h3><h3> 6 to 2 5 to 2 4 to 2 3 to 2</h3>
Remember that the the energy and the frequency of the visible colors is greatest for violet and lowest for red. That is why we refer to ultraviolet light being highly energetic ( sunburn) and infrared gogles which are used for low energy night vision ( the ultra and infra mean beyond visible spectrum)

93,000 in scientific notation is fairly simple, you're just breaking down the number a tad so you don't have to use a huge number!
BUT! In scientific notation 93,000 is 9.3x10^4 - written out that's nine point three times ten to the fourth power! (:
I hope all is well, and you pass! Good luck, rockstar! (: If you have any follow up questions, or even any comments - pm me or just let me know!
