Sorry, it has taken longer than expected to get all the data assembled and put into tables. I wanted to do a graph, but then the Excel somehow drew two lines instead of one - so I have to wait for my Mom's assistance. So that will take a while. The data seems not so linear when I draw it out - I suppose that is partly because the apparatus is not very sensitive and that the experiment needs more trials. But however inaccurate it may be, the data still illustrates my point that the thicker the glass is, the less UV gets through. So I suppose that would be alright.
The SRP is due so soon! I am so scared.
