Hi, I'm doing an investigation into the absorbance of UV light by glass of varying thickness (constant density and standard type of glass) for an assigment. However, we're not actually supposed to carry out the investigation due to time constraints, so we're meant to make up the numbers ourselves. This would be easy if I was doing a topic such as projectile motion. However, in this case I have literally no idea what figures I should include. Could anyone please help get me started by suggesting some increments of glass thickness that would demonstrate a particular relationship? I assume the graph (absorbance % against glass thickness) would plateau off at a certain point because I've heard many people say that you can still be sunburnt no matter what kind of glass it is.
