Answer:D
In absorption meter, the change in thickness of aluminium required for different samples is a function of the difference in which of the following parameters?
A. Amount B. Concentration C. Colour D. Composition
Explanation: In absorption meter, the change in thickness of aluminium required for different samples is a function of the difference in composition. A variable thickness attenuator used allows this function.
