**DrBob222**, Saturday, April 2, 2011 at 5:47pmI suppose the easiest way to look at that absorbance = A = abc and that is a linear graph. But A = log (1/T) so the graph of T versus concn can't be linear because it is a log term.

**bobpursley**, Saturday, April 2, 2011 at 5:51pmIn dummy language, it is not linear because it is logarithmic by definition.

absorbance=constant*concentration=kc

which is linear with concentration.

but absorbance=10*log P/Po=

=10log 1/Transmittance

because transmittance=P/Po

which leads to T=e^{-k*concentration}

Thus, it is not linear.
