Incandescent light globes - study design

[iGoRaw]

Do we need to know how light is produced in an incandescent light globe?
Do we need to know how this differs from a mercury vapour lamp?
Is this still on the study design?? i could not pin point it on the study design

[BasicAcid]

No we do not.

If you ever need to know, the difference is this:
Incandescent light globes work through thermal excitation of electrons. As electrons accelerate, the magnetic field they produce changes, which produces a changing electric field (the source of the emf in Faraday's law) which produces another varying magnetic field (by another form of induction)...these fields continue to produce each other through induction, and the result is probably better known as an electromagnetic wave. AKA light (:

Mercury vapour lamps work through photos of the precise energy exciting the electrons in mercury atoms to higher energy levels; as they fall back down, light of a generally single frequency is emitted.

Not a single frequency mind you but several specific frequencies

Hence the hedge "generally"
you'd notice one predominant one I would have thought

ah ok, my bad - I am too quick to critique.
