Beer's Law states that the amount of light absorbed by a substance is?

Question

inversely proportional to % transmittance

directly proportional to concentration

directly proportional to path length

all of the above

Answer 1

Directly proportional to to the concentration of the substance and the path length of the light through the solution. Oh yes and % transmittance

Answer 2

All of the above.

The more absorbed, the less transmitted. Also, Beer's Law is A = εcl, so A is proportional to c and to l.
