are you saying that darker dyes block more UV because they are usually a heavier dye?
i got that same answer from another member, that to dress for hot sunny weather you take cues from the bedouin. on a somewhat related note, bedouin seem to dress quite thick, as seen in this photo -...
im quoting you because you are a physics guru that answered this question and hopefully you can respond. okay so i asked this same question thread starter asked and i got a different answer. the answer i got was that you can't take the properties of objects in the visible spectrum as an...
so uv isn't part of visible light? on the em spectrum it shows infrared as red and ultraviolet as violet(or is it blue?). are those colors just for reference, or are they really representative of the actual color of radiation (if radiation has a color)?
as for a test, what do you think about...
which color is better at blocking UV rays?
my take on it is this analogy:
you have a room with one window, cover it with a fabric curtain that is black the room becomes very dark. cover it with that same curtain except white and the room is somewhat brighter. less light = less UV rays
