Nice post. I just have some issue with the first sentences...
When a light consisting of a certain element is switched on, the electrons of that elemental atom are excited to a higher energy level, and this process is observed due to the addition of electricity.
If I may rephrase it, light carries energy. If one bombards some atoms of a given species with light of a very specific energy, those atoms will get excited. It is also more correct to speak about electromagnetism than electricity.
All along the post, what you call electric is in fact electromagnetic.
Thank for the correction. I see that that reconstruction makes it easier to understand and more scientifically correct. Duly noted with respect to the misuse of electric, I will make sure it does not resurface in my posts related to that of light. Thank you for bringing this to my attention :)
The pleasure was for me :)
