Question
Olivia wants to find out whether a substance will fluoresce. She says she should put it in a microwave oven. Do you agree with her? Why or why not?

I do not agree with Olivia's method of testing for fluorescence by putting a substance in a microwave oven. Here are a few reasons why this approach is not advisable:
1. **Microwave Functionality**: Microwaves heat substances by exciting water molecules and other polar molecules through electromagnetic radiation. This process does not provide a means to observe or induce fluorescence in a substance, which generally requires excitation by ultraviolet (UV) light or other sources that can promote electrons to higher energy levels.
2. **Safety Concerns**: Microwaving substances that are not intended to be heated in a microwave can be dangerous. Certain materials may release toxic fumes, catch fire, or cause the microwave to malfunction.
3. **Fluorescence Testing**: To properly test for fluorescence, a more suitable method would be to expose the substance to a UV light source. Fluorescent materials absorb UV light and re-emit it at a longer wavelength (typically visible light), which can be easily observed.
In summary, the proper approach to determine if a substance fluoresces would involve using appropriate light sources and safe testing methods rather than a microwave oven.
