I wasn't sure where to post this so if this is the wrong forum please excuse my ignorance. Here's my question: By shining ultraviolet light on a bottle and noting the color that it appears to be, can a scientist then confidently calculate what color that glass bottle will appear in white light? (knowledge of the type of glass that the bottle is made of is permissible) Also, just out of curiosity, would the type of glass actually make a difference? (i.e. Pyrex vs. flint, or cystal, etc.) Finally, is there a scientific "laboratory standard" for white light? If so, how is that standard defined? Ditto for ultraviolet light. Thanks in advance for any help that you can offer.
