They typically represents different wavelengths of element due to its energy emission in the form of visible light. When an electron of that particular element move from a higher energy level down to a lower energy level, it gives off energy in the form of photon emission. Atom of a certain element has a unique electron arrangement thus it can considered that particular element's spectrum is unique.
Answer:
i think it is iron
Explanation:
its the only one that makes sense to me
Answer:
v=wavelength ×f
wavelength=v/f=455/655=0.694m
You can try recalling and rehearsing information about the memory.
