Three small questions dealing with concentrations of solutions and Beer's Law?

Question

I'm not sure about these, I've narrowed it down a bit, but I still have a couple possible answers for each. I appreciate the help in advance :)

1. What would happen to the absorbance of a solution if it was diluted to half its original concentration?
2. What would happen to the absorbance of a solution if it was placed in a cuvette that is twice as wide as the original?
3. What would happen to the absorbance of a solution if it was placed in a cuvette that was twice as tall as the original? The width was not changed.

Answer 1

1. The absorbance would decrease. I think it will decrease by one half but I am not sure.
2 and 3. Width and height have nothing to do with it. The length of the cell does.
