Answer 1

False.

Absorbance is a dimensionless quantity and does not have any units, including nanometers. It is defined as the logarithm of the ratio of incident light to transmitted light, and it is commonly expressed in terms of absorbance units (AU) or simply as a numerical value without units. Nanometers (nm) are used to measure wavelength, not absorbance.
