Introduced to this in AP Chemistry
Notes
I stands for light intensity
More concentrated a solution then that solution absorbs more light and transmits less light
Transmittance
T =
Less transmittance = more opaque
If you are good at transmitting you are bad at absorbing, good at absorbing bad at transmitting
A = -log T = -log
Beer Lambert Law - Absorbance is proportional to the path length
A = constant * length it has to travel * concentration
