Our physics class broke open a black light and a normal frosted lightbulb. We noticed that the black light filament was both longer and thinner and more tightly coiled than the normal bulb's filament. We were wondering if these differences in the dimensions of the black light's filament have anything to do with the bulb's ability to generate UV light. We would also like to know if this ability has anything to do with the resistance of the filament increasing with its longer length, and smaller cross-sectional area.
Re: How does the filament dimensions of a black light affect its working?
