How to Locate an Oil Leak Using Fluorescent Dye?
Explanation:
Among the options given, a fluorescent light would not cause the dye to glow in the same way because it emits visible light, not UV light. A strobe light typically emits visible light and would not excite the dye to fluoresce. An infrared light emits in a spectrum below visible light, not causing fluorescence in these dyes.
Therefore, the correct answer is ultraviolet light, which is commonly used to detect fluorescent substances.
