SOLUTION: The intensity, L1, of light transmitted through a certain type of tinted glass, t, mm thick can be found with the formula {{{L1(t)= L0(10)^(-.034t)}}} , where L0 is the intensity b

Question 867341: The intensity, L1, of light transmitted through a certain type of tinted glass, t, mm thick can be found with the formula , where L0 is the intensity before entering the glass. How thick should the glass be in order to block 30% of the light?
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
If you block 30% of the light, then the light intensity after it passes through the glass will be 100 - 30 = 70%. Therefore, L1(t) = 0.7*L0 (basically 70% of the original light intensity L0 coming in). Plug this is in and solve for t

This is the approximate thickness.
