# An issue with Bouger-Lambert Law

I'm certain that I misunderstand this law. It states that:

$$I = I_o e^{-kb}$$

and after rearranging:

$$A = ln{I_o}-lnI$$

where $A$ stands for absorbance.

1) Does is mean that when the intensity of the exiting light is very low than the absorbance is extremely high?

2) But from the graphs in my textbook, I've seen absorbance which was up to 1 or 1,2. Does it mean that most objects give little "resistance" to light?

3) My textbook says that molar absorption coefficient depicts the probability that photon will excite the energy states (not their words exactly :) ). Than why is f(c) = epsilon a constant function? Shouldn't more concentration increase the probability of change in energy states in some for example molecule?
